Color-blocking is the cheapest-looking easy idea and the most expensive hard one.

On a mood board it costs nothing.

Drag a red rectangle over the chest and a cream rectangle over the sleeve, and the hoodie suddenly looks like a brand instead of a blank.

That is why so many first collections reach for it.

On a cutting table it costs plenty.

Every color you add is a separate roll of fabric, dyed in a separate bath, cut in a separate lay, and tracked as a separate lot.

Every seam between two colors is a seam a customer will stare directly at, because contrast draws the eye to exactly the line you least want them examining.

So the failures are specific and predictable.

Two panels of “the same” navy that read as two different navies under shop lighting.

A raglan seam that sits a centimeter lower on the left than the right, which nobody notices on a solid hoodie and everybody notices when one side is black and the other is cream.

A cream sleeve that shrinks harder than the black body after the first wash, because it came off a different base fabric.

None of those are freak accidents. They are what happens when a color-block spec is written like a solid-color spec.

This guide walks the garment from design through cutting, sewing, trims, and cost and ends with a checklist you can hand to any factory, ours, or somebody else’s.

Chapter 01

How is a color-block hoodie actually built?

A color-block hoodie is a construction decision, not a print decision.

The color lives in the fabric, not on top of it which means the design has to be resolved on the pattern table before a single stitch is sewn.

Start with the thing most brands get wrong in their first brief.

You can put two colors on a hoodie in two completely different ways.

You can print a block of color onto a solid garment, or you can cut and sew the block as a separate piece of dyed fabric.

They look different, they cost different, and they fail different.

A printed block sits on the surface. It has a slight hand to it, it can crack over time, and it stops at the seam because a print cannot wrap a shoulder cleanly.

A cut-and-sew block is the garment. It wraps, it drapes, it wears exactly like the rest of the hoodie, and it does not degrade in the wash.

It is also the only way to get a color to travel around a curve, a sleeve, a hood, or a side body and still look intentional.

When people say “color-block hoodie,” they almost always mean cut-and-sew.

That is what this guide covers.

If your design is a rectangle of color that could live on the front chest and nowhere else, you probably want screen printing or another decoration method instead, and you will save a lot of money.

The pieces a hoodie is cut from:

A standard pullover hoodie is not one shape. Before any color is involved, it is already a stack of separate pattern pieces:

  • Front body one-piece, or two if there is a center-front seam or a zip.
  • Back body is usually one piece.
  • Sleeves two, either set-in or raglan.
  • Hood with two or three panels, plus lining if it is double-layered.
  • Pocket one kangaroo piece, or two welt pieces.
  • Ribbing cuffs, hem band, and sometimes a neck binding.

That is already seven-plus pieces on a plain hoodie.

Color-blocking does not invent new pieces from nothing.

It does two things: it assigns existing pieces to different colors, and where the design demands it, it splits a single piece into two or more.

The two kinds of color-block:

This distinction is worth holding onto, because it is the biggest cost lever in the whole garment.

Type What it means Cost impact
Piece-level blocking Existing pattern pieces get different colors. Black body, cream sleeves. Grey body, navy hood. Low. No new seams. Same sewing operations as a solid hoodie.
Split-panel blocking A single piece is cut into two or more. A chest stripe across the front body. A two-tone sleeve. Higher. Every split adds a seam, an operation, and a QC point.

Piece-level blocking is close to free.

If your hoodie already has separate sleeves, cutting those sleeves from a different roll costs you nothing in labor.

You are paying for a second fabric lot, not for extra sewing.

Split-panel blocking is where the money goes.

Cut a horizontal band across the chest, and you have turned one front body into three pieces, added two seams that run the full width of the garment, and created two lines that must align perfectly with their partners on the back and the sleeve.

That is real labor, and it is where the construction method you choose starts to matter.

How do the panels come together on the floor?

  1. Pattern split. The pattern maker takes the base block and cuts the panel lines into it, adding seam allowance on both sides of every new line. This is the step where a “1 cm stripe” quietly becomes a 2.5 cm stripe, because nobody added the allowance.
  2. Separate lays. Each color gets its own marker and its own lay. Black fabric is spread and cut for the black pieces. Cream is spread and cut for the cream pieces. They are never cut together.
  3. Bundling by lot. Cut pieces are bundled and ticketed with the lot number of the roll they came from. This ticket is the single most important piece of paper in a color-block order.
  4. Joining. The panels are sewn into sub-assemblies front body, back body, and sleeves before the garment is closed. Panel seams are usually overlocked and then topstitched or coverstitched flat.
  5. Closing and finishing. Shoulder, side seams, sleeve attach, hood attach, ribbing, drawcord, eyelets. Same as any hoodie, but with the added job of keeping every color junction lined up.

The order of operations matters more than most brands realize.

Panels are joined before the garment is closed, which means a misaligned panel seam is discovered when the garment is already half-built.

Catching it at the sub-assembly stage costs a re-sew.

Catching it at final QC costs a garment. The stitching and finishing choices made here decide how forgiving the whole run will be.

Chapter 02

Designing panel splits that flatter the body:

A panel line is a horizontal or diagonal rule drawn across a human torso.

It will be read as a measurement of that torso.

Put it in the wrong place and the hoodie will look badly proportioned even when it is perfectly made.

This is the part of color-blocking nobody warns brands about.

On a flat tech pack, a chest stripe at 40% of the body length looks balanced.

On a real person it can land directly across the widest part of the chest, cut the torso into two stubby halves, and make a size L look like a size L wearing a size M.

The garment is not defective. The line is just in a bad place.

Where does the eye actually go?

A few things hold true across almost everybody:

  • Horizontal lines widen. A high-contrast horizontal band adds visual width wherever it lands. Put it where the wearer wants width on the chest and the shoulders, not at the waist.
  • The worst place is the mid-belly. A band that lands between the navel and the hem is the single least flattering position on a hoodie, and it is where a lazy 50/50 split naturally falls.
  • Diagonals are slim and complicated. A diagonal panel reads as movement and is more forgiving on the body. It is also harder to sew, because a diagonal seam crosses the fabric on a partial bias and wants to stretch.
  • Vertical splits lengthen. A center-front or side-body vertical panel makes the torso read longer. Cheap to design, easy to sew, badly underused.
  • Yokes flatter almost everyone. A shoulder yoke, a panel that runs across the upper chest and back, above the armhole, is the safest color block on a hoodie. It sits above the body’s widest point, and it frames the face.

The splits that actually work on a hoodie:

Split Where it sits Difficulty
Contrast sleeves Whole sleeve in a second color. Raglan makes it look designed; set-in makes it look like a baseball tee. Easy, no new seams
Contrast hood Hood, or hood lining only. Lining is the quiet-luxury version: solid outside, surprise inside. Easy
Shoulder yoke Across the upper chest and back, above the armhole. Flattering on nearly everybody. Medium: two new seams must align at the shoulder
Chest band Horizontal band across the chest. Keep it high above the fullest chest point, not below. The medium must align across the front, back, and sleeve
Vertical / half-and-half The left half is one color, and the right half is another. Bold, easy to sew, and very easy to get wrong at the hood. Medium
Diagonal panel Angled across the body. Highest design payoff, hardest to control. Hard bias stretch, alignment across side seams

Design rules we hand to brands:

  1. Dimension every line from a fixed point. Not “chest stripe” “top edge of stripe sits 22 cm down from high point shoulder, measured at center front, on size M.”A line described in words is a line the factory will guess at.
  2. Grade the line; don’t fix it. A stripe at a fixed 22 cm on every size will sit at the chest on an XS and at the belly on a 3XL. Panel lines must be graded with the body, the same way the pattern is.
  3. Decide what happens at the sleeve. If a chest band runs to the armhole, does it continue onto the sleeve? If yes, it must meet the sleeve line exactly. If not, say so; otherwise, you will get a factory’s guess.
  4. Decide what happens at the hood. Vertical and diagonal splits look great on the body and then hit the hood and fall apart. The hood is a curved three-panel object. A line that runs into it needs its own drawing.
  5. Check it on the biggest size, not the sample size. Everything looks fine on the M fit sample. Ask for the panel line to be mocked on the largest size you will sell before you approve it.

The method

The Three-Match Check:

Almost every color-block hoodie that fails inspection fails on one of three matches. Not on stitching quality. Not on fabric quality. On a match.

We run every color-block order against the same three gates before it ships.

If a garment clears all three, the color-blocking is right. If it fails one, no amount of good sewing elsewhere will save it because the contrast seam is exactly where the customer’s eye lands.

Match 01

Shade match:

Every piece of a given color comes from one dye lot. Chapter 04.

Match 02

Line match:

Every panel seam meets its partner at the junction. Chapter 05.

Match 03

Hand match:

Every color is the same base fabric, same weight, and same shrink. Chapter 08.

Chapter 03 · Match 01

Cutting every color from a matched lot:

Shade mismatch is the number-one color-block defect, and it is almost never a dyeing failure. It is a tracking failure.

Two panels of the same navy came from two different dye baths, and nobody caught it until the garment was sewn.

Here is the thing brands find hardest to believe: the same color is not the same color twice.

Fabric is dyed in batches. A dye lot is one bath, one recipe, one run.

The next bath of the same recipe will land close but not identical.

Water temperature, dwell time, the age of the dye, and the specific bale of yarn all move the result a fraction.

On its own, that fraction is invisible. Nobody has ever compared two hoodies from different production runs and noticed.

But a color-block hoodie puts the two fractions next to each other, across a seam, on the same garment. Now it is not a fraction. It is a defect.

Where does the mismatch sneak in?

  • The order ran short. Halfway through cutting, the black roll runs out. A second black roll is pulled from stock. It is the same reference number, a different lot. Half the run now has a hood that reads warmer than the body.
  • Panels were cut on different days. Same color, same reference, but a fresh roll was opened between the two layers.
  • Sample and bulk came from different lots. The approved sample is perfect. Bulk arrives, and the cream is a half-shade greener. Both are “cream.” Only one was approved.
  • Two components were sourced separately. The body fabric was dyed by one mill and the rib for the cuffs by another. Getting a rib to match the body is its own problem, and it is the one people forget entirely.

How does the lot get locked?

  1. Calculate consumption with a real cushion. Fabric for a color-block order is booked per color, per lot, with a wastage allowance built in. Running out mid-cut is not a scheduling problem. It is a shade problem.
  2. Book one lot per color per order. Every black panel in the run comes from a lot A. Every cream panel from the lot B. No exceptions, no top-ups.
  3. Ticket the bundles. Cut pieces carry a lot of tickets from the cutting table through to the sewing line. An operator can see, at the machine, which lot they are joining.
  4. Approve a lab dip, then a bulk swatch. The lab dip approves the recipe. The bulk swatch approves the actual roll that will be cut. They are two separate approvals, and skipping the second is how “approved” colors go wrong.
  5. Check under more than one light. Two shades can match under factory light and split apart under daylight or LED retail lighting. This is metamerism, and it is the reason a shade check is done in a controlled light box, not by eye at the table.
  6. Cross-match the rib. Rib takes dye differently than fleece. Approve the rib against the body fabric, side by side, before bulk, not against a Pantone chip.

If you are choosing your colors from scratch rather than matching an existing palette, the sequence of lab dips and bulk approvals is worth understanding in full; our color control and dye approval process covers it.

Chapter 04 · Match 02

Keeping seam lines crisp and aligned:

On a solid hoodie, a seam that sits 4 mm off is invisible.

On a color-block hoodie it is the first thing anyone sees, because a contrast seam is a drawn line, and the human eye is very good at spotting a line that does not meet its partner.

Contrast is a magnifying glass. Everything you accept on a solid garment gets audited on a blocked one.

There are three ways a panel line goes wrong, and they have different causes.

01. The line wanders:

The seam is not straight. It rises or dips across the width of the garment.

Usually this is a feeding problem: knit fabric stretches under the presser foot, and if the top layer feeds faster than the bottom layer, the seam curves.

On a solid hoodie you would never see it. Against a contrast color, it looks like a mistake, because it is one.

The fixes are mechanical: correct differential feed on the overlock, a walking foot where needed, tape or fusible stabilizer on long horizontal seams, and operators who are actually experienced on knits.

A stabilized seam on a fleece body is the difference between a line and a wave.

02. The line does not meet its partner:

This is the alignment failure, and it is the one that kills the garment.

A chest band on the front body has to meet the chest band on the back body at the side seam.

If one is 5 mm higher, the line steps.

A yoke on the front has to meet the yoke on the back at the shoulder.

If the sleeve carries the band, all three have to land at the same height at the armhole.

The control for this is notching.

Every panel seam gets a notch cut into the pattern at the junction points.

The operator matches notch to notch, not eye to eye.

If the pattern has no notches at the color junctions, the factory is aligning by judgment, and judgment varies by operator, by hour, and by how many pieces are left in the bundle.

03. The seam is bulky, or it grins:

A “grin” is when the seam pulls open under tension and you can see the stitch line or a flash of the other color’s raw edge.

On a contrast seam, a grin shows a stripe of the wrong color. It is ugly and it is very visible.

The fixes are construction choices: correct stitch density, matched thread tension on both fabrics, and a topstitch or coverstitch that locks the seam allowance down flat.

Which seam finish you use here is a real decision, and it changes both the look and the durability of every color junction.

The seam and stitch construction guide covers the options in detail.

What QC actually checks on a blocked garment?

  • Junction step. Panel line at the side seam, front to back. Tolerance is tight; a step you can see is a step you reject.
  • Symmetry. Left sleeve panel against right sleeve panel. Same height, same width.
  • Straightness. The line measured at three points across its run, not one.
  • Seam grin. The seam stretched by hand. If the other color flashes through, it fails.
  • Thread color at the junction. Which color thread crosses the boundary, and does it read as intentional?
  • Lot ticket. Yes, again. Checked at QC as well as at cutting.

Chapter 05

Contrast trims, drawcords, and zips:

The trims are where a color-block hoodie either resolves into a designed object or falls apart into a pile of colors.

They are also the cheapest part of the garment to get right and the most commonly left blank on a tech pack.

You have chosen two or three body colors.

Now you have to decide what color the drawcord is. And the eyelets. And the thread. And the zip tape, and the zip teeth, and the puller, and the rib, and the label.

That is seven more color decisions. Leave them off the spec, and the factory will choose for you sensibly, but not necessarily the way you would have.

The three strategies that work:

Strategy How it works Reads as
Tie to the dominant Every trim matches the largest body color. Drawcord, rib, thread, and zip all in the base. Calm, premium, safe. The panels do the talking.
Tie to the accent Trims pick up the smallest, boldest panel color and repeat it. Deliberate and designed. The accent looks chosen, not leftover.
Introduce a fourth. Trims are a color that appears nowhere else on the body. High risk. Works when it is a neutral or a signature brand color. Otherwise, noise.

The failure mode is having no strategy at all:

A black drawcord because the body is black, cream rib because the cuffs are cream, and a grey zip because that was in stock.

Every piece is defensible on its own; the whole thing is incoherent.

Trim-by-trim:

  • Drawcord. Flat or round, and the two read completely differently; flat is heavier and more contemporary. Specify the color, the width, and the tip (metal, plastic, or knotted). Two-tone cords exist and are an easy way to tie two panel colors together in one component.
  • Eyelets. Metal or stitched. Metal in an antique or gunmetal finish reads more expensive than shiny silver on almost every colorway. If the hood is one color and the body another, decide which the eyelet sits on and match to that.
  • Rib (cuffs and hem). Rib is a color decision and a matching problem. It is a different construction from the body fleece, so it takes dye differently and must be approved side by side against the body (see Match 01.)
  • Thread. At a color junction, the topstitch thread has to be one color or the other. Matching the darker panel usually hides more. Deliberately contrasting a cream stitch on black is a strong look, but it is unforgiving of any wander in the seam.
  • Zip (on zip-through styles). Three separate colors: tape, teeth, and puller. Tape matching the placket is standard. A contrast tape is a genuine design move. Metal teeth on a heavyweight blocked hoodie is one of the cheapest ways to add perceived value.
  • Labels and tags. The neck label sits on whatever color the back hood or yoke is. A woven label designed for a white interior can look wrong on a black one. Check it in situ, not on a sheet.

From the floor:

A trim decision that visibly changed a color-block sample, e.g., drawcord tip or zip tape swap. Short, concrete, and about a real order.

Chapter 06

Why do more panels cost more?

Color-blocking adds cost in four places, and only one of them is fabric.

Understanding which is which lets you buy the look you want without paying for complexity you do not need.

Brands usually assume the extra cost of a color-block hoodie is the extra fabric.

It is not. Fabric is the smallest part of it.

The four cost drivers:

  1. Extra sewing operations. Every panel seam is a machine operation with a time attached. A split-panel design adds seams; seams add minutes; minutes are the largest single input in a garment’s cost. This is the one that actually moves the price.
  2. Lower fabric efficiency. Cutting three colors means three markers and three lays. A marker for a handful of small accent panels wastes more fabric proportionally than a marker for a full body. Efficiency drops, and wastage rises.
  3. Minimums per color. This is the trap. Each color needs enough fabric to justify a dye lot. A 50-piece order in three colors is not one 50-piece fabric; it is three separate fabric commitments, and the smallest one may sit well below the mill’s minimum. That surplus is priced into your garment.
  4. QC and rework. More junctions means more inspection points, more in-line checks, and statistically more rework. A blocked garment fails inspection for reasons a solid one simply cannot.

How to buy the look for less?

  • Block at the piece, not the panel. Contrast sleeves and a contrast hood give you 80% of the color-block impact for close to none of the sewing cost. Start here.
  • Use a color you are already buying. If you are running three styles this season and two share a base color, block with that color. You are then buying more of one lot, not committing to a new one.
  • Put the third color in the trims. A contrast drawcord and eyelet costs a fraction of a contrast panel and reads as just as intentional.
  • Keep the accent panel small but not tiny. Small panels are cheap in fabric and expensive in minimums. There is a floor below which a color stops you from saving anything.
  • Line the hood instead of blocking the body. A contrast hood lining is a quiet, premium move, and it is one extra piece from a color you may already have.

None of this changes the fact that a color-block hoodie is a more expensive garment than a solid one.

It should be. It is a harder thing to make.

But the difference between a well-designed block and a badly designed one, at the same retail price, is often just where the seams were put.

From the floor:

A trim decision that visibly changed a color-block sample, e.g., drawcord tip or zip tape swap. Short, concrete, and about a real order.

Chapter 07 · Match 03

Keeping the fabric consistent across colors:

Every panel color must be the same base fabric. Same knit, same weight, same fabric blend, same finish.

If it is not, the hoodie will feel like two garments, and after the first wash, it will look like two garments.

This is the failure that does not show up at QC. It shows up at the customer’s house.

Here is how it happens. The brand wants a black body and a cream sleeve.

The mill has black in the 380 GSM brushed-back fleece they usually run.

The cream is out of stock in that quality, but there is a cream in a 340 GSM that is “basically the same.”

Somebody says yes, because it is 40 GSM and the garment ships on time.

Then the hoodie is washed.

What goes wrong when the base fabric drifts?

  • Differential shrinkage. The two fabrics shrink at different rates. A sleeve that shrinks 1% more than the body pulls the armhole seam, puckers the junction, and twists the garment. This is irreversible, and it happens on wash one.
  • Weight and drape mismatch. A lighter panel hangs differently than a heavier one. The garment stops falling as a single object.
  • Hand mismatch. One panel is brushed, and one is not. The wearer can feel the seam boundary with their hand. This is the fastest way for an expensive hoodie to feel cheap.
  • Different pilling and fade. Different fabric blends age differently. After six months, one panel looks worn and the other looks new.
  • Different stretch. A panel with more elastane behaves differently at the seam, and the seam is where the two meet.

The rule, and the one exception:

The rule: every panel color comes from the same base quality. Same GSM, same blend, same knit construction, same finish. Only the dye changes.

This is non-negotiable on any panel that shares a seam with another panel on the body.

If a color is not available in your base quality, you have two honest options: change the color or change the base fabric for the whole garment. You do not mix.

The exception: a hood lining, or an internal panel that shares no visible seam boundary with the outer, can be a different quality.

That is a deliberate construction choice, not a compromise. It still must be tested for shrinkage against the shell.

Which base fabric you build on is upstream of all of this, and it constrains what colors you can even get.

Not every fleece quality is stocked in every shade; the hoodie fabric guide covers what each quality is good for and where the color availability tends to sit.

Testing before you commit:

  1. Wash test every color, not one. A shrinkage test on the black is not a shrinkage test on the cream. Both fabrics get washed and measured.
  2. Wash the sewn junction. A stitched panel seam, washed, and inspected for puckering. This is the test that actually predicts what the customer will see.
  3. Compare hand side by side. Two swatches, same hand, eyes closed. If you can feel the difference, so will the wearer.
  4. Check pilling and crocking per color. Dark shades on light panels can transfer color at the seam under abrasion. This is worth testing on any high-contrast block.
  5. Approve the sample after washing, not before. A color-block pre-production sample that has not been washed has not been tested. Ask for a washed sample.

From the floor:

A real differential-shrinkage case, ideally caught at the wash test. Include the two GSMs involved and the measured shrink difference

Chapter 08

The spec checklist for a custom color-block hoodie:

Hand this to any factory. Everything on it is something a factory will otherwise have to guess at, and every guess is a place your hoodie can come back different from the one in your head.

A color-block spec is a solid-hoodie spec plus the answers below.

If you can fill this in, you will get a quote you can trust and a sample that looks like your drawing.

  • Base fabric of one quality, stated once: GSM, fibre blend, knit construction, and finish. The same for every panel color. Name it before you name the colors.
  • Colorway list with references: Every color by Pantone TCX or an approved physical swatch. “Cream” is not a color. Confirm each shade is available in your base quality.
  • Panel map which piece is which color: A flat sketch, front and back, with every pattern piece labelled with its color. Include the hood, the pocket, and the rib.
  • Panel line positions, dimensioned : Every split line is measured from a fixed point (high point shoulder, center front). State the size the measurement refers to.
  • Grading rule for the panel lines: How the line moves across the size range. If you do not specify this, the line will be fixed, and it will land wrong on your largest sizes.
  • Junction behavior: What happens where the line hits the side seam, the armhole, the sleeve, and the hood. Draw it. Do not describe it.
  • Seam finish at color junctions: Overlock plus coverstitch, flatlock, or topstitch. And which side the seam allowance is pressed toward.
  • Thread color at every junction: Match to the darker panel, match to the lighter, or deliberate contrast. State it per seam, not per garment.
  • Trim colors, all of them: Drawcord (type, width, tip), eyelets (material, finish), rib, zip tape, zip teeth, puller, and labels. Seven decisions. Make them.
  • One dye lot per color, in writing: State on the PO that all pieces of a given color must come from a single lot, and that lot substitution requires your approval.
  • Lab dip and bulk swatch approvals: Two approvals, not one. And rib approved against body fabric, side by side, under controlled light.
  • Washed pre-production sample: Ask for the PP sample after a wash cycle. Shrinkage was measured per color, and the panel junctions were inspected for pucker.
  • Alignment tolerance, stated: The maximum acceptable step at a panel junction, in millimeters. If you do not state it, you cannot reject it.
  • Largest-size mock-up before approval: See the panel line on your biggest size, not just the sample size, before you sign off.

Fourteen lines. Most brands send us three of them.

The ones who send all fourteen get a first sample that is close, a second sample that is right, and a bulk run that matches the sample, which is the entire point of the exercise.

Questions we get asked

Our minimum is 50 pieces per style.

A color-block hoodie counts as one style even though it uses several fabric colors, so the 50-piece minimum still applies.

The thing to watch is not the garment minimum but the fabric minimum:

Each panel color needs enough fabric to justify its own dye lot, so a design with four colors at 50 pieces can leave you paying for surplus fabric in the smaller colors.

Fewer colors at low volume is usually the better buy.

Usually yes, because the color is cut and sewn into the garment rather than applied on top of it.

The extra cost comes from additional sewing operations, lower fabric cutting efficiency, a separate dye lot per color, and more inspection points.

A printed block is cheaper, but it sits on the surface, cannot wrap a curve, and can crack over time.

A cut-and-sew block wears exactly like the rest of the garment.

Because they came from different dye lots.

Fabric is dyed in batches, and two batches of the same recipe will land slightly apart.

On separate garments nobody notices.

On the same garment, across a seam, the difference reads as a defect.

The fix is to book one dye lot per color for the whole order, ticket the cut bundles with their lot number, and check shades in a controlled light box rather than by eye.

No. Every panel that shares a visible seam with another should be the same base quality, same GSM, same blend, same knit, and same finish, with only the dye changing.

Mixing weights causes differential shrinkage, which puckers the panel seams on the first wash and twists the garment.

A hood lining that shares no visible seam boundary with the outer shell can be a different quality, but it still needs to be shrinkage tested against the shell.

High, above the fullest point of the chest, rather than at the mid-belly.

A high-contrast horizontal line adds visual width wherever it lands, so it should land where width is wanted.

The line must also be graded across the size range rather than fixed at one measurement; otherwise, a stripe that sits at the chest on a small will sit at the belly on a 3XL.

Technically, as many as you can afford.

Practically, cost and risk climb sharply past three. Each color adds a dye lot, a separate cutting lay, and a fabric minimum, and each extra panel adds sewing operations and junctions that have to align.

Most brands get better results putting two or three colors into the body and a third or fourth into the trims drawcord, eyelets, or zip tape, where it costs a fraction as much and still reads as deliberate.

Piece-level blocking gives an existing pattern piece its own color rather than splitting a piece into new panels.

Contrast sleeves and a contrast hood are the two cheapest examples, because a hoodie already has separate sleeves and a separate hood.

There are no new seams and no new sewing operations, so you pay for the second fabric lot and almost nothing else.
