How to Choose Bag Colors That Match Your Brand (and Print Well)

Why colour is a sourcing decision, not a design afterthought

Colour is usually treated as the last decision on a bag programme and behaves like the first. The moment a colourway is chosen, a chain of consequences starts: whether the fabric exists in stock, whether a dye lot has to be created, how long that takes, how the logo will read against it, whether the ink needs an underbase, and whether the dye can be documented for the destination market. A colour chosen without reference to those consequences can add 15-25 working days to a schedule that was already tight.

The second reason colour belongs early is commercial. Backers choose between colourways, and colourways are what stretch goals are made of. That means the colour plan is also a demand plan, and a demand plan interacts directly with the 500 pcs minimum per style and colourway. Choosing four colourways when the campaign will only sell two creates surplus in the two that do not move. The material customisation page covers the fabric side of the same decision.

Brand colour versus fabric colour: why they never match exactly

A brand colour is defined for screens and print: an HEX value, an RGB build, a Pantone reference on coated paper. A fabric colour is dye absorbed into a fibre, seen through a weave, under a coating, in whatever light the room happens to have. The two cannot be identical, and promising backers an exact match sets up a disappointment that no production team can prevent. What can be promised is a controlled, approved shade with a stated tolerance.

Metamerism deserves a specific warning because it is the cause of the most frustrating colour disputes. Two swatches can match under office lighting and visibly differ in daylight. Approve under the light your backers will use, which for a bag is usually daylight or warm indoor light, and record the conditions in the approval note so the reference is reproducible.

Pantone, lab dips and the shade approval process

The approval sequence for a custom colour is short but must be followed in order. You nominate a Pantone reference, the mill produces a lab dip — a small dyed sample — against that reference, you approve or reject the dip, and only then is the bulk lot dyed. Skipping the dip and asking for the reference directly is the fastest route to a shade dispute, because a mill will interpret the reference and its interpretation may not be yours.

1. Nominate the Pantone reference with the coating system, for example Pantone TCX for textiles rather than a coated-paper reference.
2. Request a lab dip on the actual fabric construction at the actual weight, not on a generic swatch card.
3. Review the dip under two light sources and record which one the approval is based on.
4. Approve or reject in writing within 24 hours; every day of deliberation is a day added to the calendar.
5. State the tolerance you will accept, usually plus or minus one Pantone step on fabric.
6. Keep the approved dip sealed and dated as the reference for the bulk lot and for inspection.

Stock colourways versus custom dye: cost and calendar

This is the decision with the largest calendar consequence on the whole colour question. Stock colourways already exist: the fabric is in the warehouse, the shade is known, and sampling proceeds inside the standard 6-10 working days. Custom dye means the mill produces a lot to your reference, which adds 15-25 working days before cutting begins, usually carries a mill minimum that exceeds your bag quantity, and introduces a shade-approval step that can require a second dip.

The compromise most campaigns should take is a stock colourway close to the brand colour with branding carrying the exact brand shade. A stock charcoal shell with a brand-coloured woven label and a brand-coloured print reads as on-brand to backers, while keeping the schedule intact. Custom dye becomes the right answer when the brand colour is contractual, when a retail buyer requires it, or when the run is large enough that the mill minimum stops mattering.

How colour behaves on each fabric family

Each fabric family takes colour differently, and knowing the differences prevents a design that works on one material and fails on another. Polyester takes disperse dye well and holds saturated shades; nylon is similar but can show barre, a subtle stripe caused by yarn variation; cotton canvas takes reactive or pigment dye and reads softer and more matte; and recycled polyester carries a base tint from its feedstock that limits how light and how clean a shade can be.

Recycled content deserves one further note. If you are making a sustainability claim, the rPET base tint is part of the story rather than a defect, and backers generally accept it. What they will not accept is a claim that cannot be documented, so ask for GRS transaction documentation at the same time as the swatch. Our QA and QC page lists the documentation checks that run before release.

There is also a practical photography point that interacts with colour choice. Deep matte shades photograph well in a studio and poorly in a backer's phone snapshot, where they lose edge definition; mid-tones with a slight sheen tend to hold up better across both. If your campaign images will be shot quickly and your backers will post their own, choose a shade that survives a mediocre camera, because those images are what the next wave of backers will see.

Dark bases, light prints and underbase white

Printing a light logo on a dark bag is the most common visual request on campaign programmes and the one most often underestimated. Ink sits on the surface of the fabric, so a white or pale print on a navy shell will be partly absorbed and will read dull unless an opaque white underbase is printed first and the colour laid over it. That is two passes instead of one, which changes cost, hand feel and the final shade.

• Budget an extra screen and an extra pass for any light print on a dark base.
• Approve the printed result, not the ink colour: the underbase changes what the top colour reads as.
• Expect a slightly thicker hand feel where an underbase is used; test it on the sample rather than in theory.
• Consider embroidery or a woven label on dark bases, since both avoid the opacity problem entirely.
• Where a print must be crisp and small, a heat transfer can outperform screen print on dark fabric.
• Check the print after washing or abrasion if the bag will be used hard, since underbases can crack.

Contrast rules for logos on coloured fabric

Legibility on fabric is governed by more than contrast ratio, because the weave breaks up fine detail and the base colour shows through the ink slightly. The practical rules below keep a mark readable at the sizes bags actually use. They matter most on the small placements — a woven label, a strap print, a zip pull — where the difference between legible and muddy is a millimetre.

Colour fastness: crocking, washing, light and what to test

Colour that looks right on day one and migrates by week three is a warranty problem. Fastness is measured in several independent ways, and a fabric can perform well on one and poorly on another. Crocking is colour transfer under rubbing, which is the failure backers notice when a dark bag marks a light shirt. Wash fastness is colour loss or bleeding in laundering. Light fastness is fading under UV. Perspiration fastness matters on straps and back panels.

Deep saturated shades — bright reds, deep navies, strong blacks — carry the highest crocking risk, and dark linings under light shells carry the highest migration risk in storage. If your design combines both, ask for the fastness test to be run on the actual combination rather than on the fabrics separately. Deep shades also raise restricted-substance questions in some markets, which is the subject of the compliance section below.

Colour also carries a psychological dimension that is easy to overthink and unwise to ignore. Neutral shells — black, charcoal, navy, olive — dominate bag categories because they survive daily use and match more outfits, which reduces buyer hesitation. Bright and seasonal shades convert well in a campaign context and can photograph beautifully, but they narrow the audience and they show soiling faster. A workable pattern is a neutral hero with a bright accent: a black shell with a brand-coloured label, lining or webbing, which reads as considered without narrowing the market.

Colourway planning inside the 500 pcs minimum

The minimum is 500 pcs per style and per colourway, which makes the colourway plan a financial decision as much as an aesthetic one. Two colourways in one style is two 500 pcs commitments unless a single run with a colour split is negotiated, and three colourways is three. The safe pattern for a first campaign is one hero colourway at the full first run, with additional colourways priced during the original RFQ and ordered only once the pledge manager shows real demand.

A useful tactic is to make the second colourway the stretch goal. Backers unlock it, the campaign gains a news moment, and because it was priced in the original RFQ it can be confirmed with one email rather than renegotiated. The low minimum page explains how splits and stretch colourways are handled inside the minimum.

Shade consistency across a run and between lots

A run of 500 units is usually dyed in one lot, which keeps shade consistent. Larger runs, split runs and re-orders introduce the risk of more than one lot, and different lots of the same nominal colour can differ visibly. That is why the approved swatch and the approved pre-production sample matter so much: they are the reference that settles whether a second lot is acceptable.

• Ask for the dye lot number to be recorded on the packing list and the material record.
• Require panels within one bag to come from the same lot; mismatched panels are a visible defect.
• On re-orders, present the original approved swatch and ask for a dip against it before bulk dyeing.
• Define shade variation as an inspection defect class, with the tolerance stated in the purchase order.
• Where a run spans two lots, ask for them to be packed separately and labelled, so fulfilment can avoid mixing.
• Photograph the approved reference under consistent lighting so remote comparison is meaningful.

Dyes, restricted substances and compliance documentation

Colour and compliance intersect at the dye. Certain azo dyes, some disperse dyes and heavy-metal-containing pigments are restricted in major markets, and deep shades are the higher-risk end of the palette. If the destination is the EU, REACH applies; California sales bring Prop 65; children's products in the US bring CPSIA; and OEKO-TEX Standard 100 is the voluntary textile safety label many retailers ask for.

• Name the destination market in the RFQ so dye selection happens once, at the start.
• Ask for OEKO-TEX Standard 100 certification on the fabric where the market or channel expects it.
• Request REACH and Prop 65 declarations for dyed fabric, hardware and printed decoration.
• If you claim recycled content, ask for GRS transaction documentation at the same time as the swatch.
• Keep the documentation with the tech pack; it is needed per shipment, not per campaign.
• Check printed inks and coatings as well as fabric, since restrictions apply to the finished article.

Colour checklist for the RFQ

Send this list with the tech pack and the artwork, and the colour question will be answered in the quotation rather than in a second round of samples. Every line below prevents either a delay or a dispute, and none of them take more than a few minutes to complete.

• Pantone reference for every brand colour, with the coating system stated, for example TCX for textiles.
• Confirmation of whether each colourway is stock or custom-dyed, with the added days stated separately.
• Lab dip requested on the actual fabric construction, at the actual weight, after coating.
• Tolerance stated for shade approval, usually plus or minus one Pantone step.
• Light source recorded for the approval, so the reference can be reproduced later.
• Fastness targets stated: crocking, wash, light and perspiration grades.
• Print method confirmed per placement, including whether an underbase white is required.
• Contrast tested against the actual shell shade, not against a white swatch card.
• Colourway quantities stated separately, remembering the 500 pcs minimum per colourway.
• Compliance documentation requested for the destination market, named standard by standard.

If you want the colour decision reviewed before it is frozen, request a quotation with your Pantone references and target fabric attached. Our production team will confirm which shades are available from stock, which require a dye lot, and what each costs in days. The print and embroidery page covers how those shades behave under each decoration method, and the custom tote page shows a worked colourway plan on a simple format.
