# Pantone Colour Matching in Bulk Workwear: Getting It Right

**Colour matching in workwear runs on three things: the right Pantone reference (TCX for fabric, not the paper swatch), a physical lab dip approved before bulk, and a written tolerance — normally Delta E of 1.5 or better under D65 lighting. Custom dyeing adds 5–12% to the garment cost and requires 300–1,000 pieces per colour, but it is the only way to guarantee that next year's delivery matches this year's.**

## Key takeaways

- **Use TCX references for fabric.** Paper swatches do not dye predictably on polyester or cotton.
- **Approve a physical lab dip, not a screen.** Colour on a monitor is not a specification.
- **Set a Delta E tolerance in writing** — 1.5 or better for brand colours, 2.0 for general use.
- **Dye lots vary.** Keep a sealed retained sample for every approved colour.
- **Check under the light the garment will live in**, not only under office lighting.

## 1. Which Pantone system to use

| System | What it is | Use it for | Do not use for |
| ------ | ---------- | ---------- | -------------- |
| Pantone TCX | Textile cotton standard | Fabric dyeing, garment colour matching | Printing on paper |
| Pantone TPG / TPX | Paper standard for textiles and fashion | Design references and merchandising | Dyeing fabric directly |
| Pantone PMS C / U | Graphic print standard, coated and uncoated | Screen print inks, packaging, signage | Fabric dyeing |
| Thread colour cards | Embroidery thread references | Embroidery colour selection | Fabric dyeing approval |

The most common error in workwear branding is sending a PMS C reference and expecting the fabric to match it. A coated print standard and a dyed textile behave differently; give the mill a TCX reference, and give the printer a PMS reference.

## 2. The lab dip process, step by step

| Step | What happens | Typical time |
| ---- | ------------ | ------------ |
| 1. Reference | You send the Pantone TCX code or a physical swatch | Day 1 |
| 2. Lab dip | The mill dyes small swatches in two or three trial shades | 5–10 working days |
| 3. Review | You compare against the reference under controlled lighting | 1–3 days |
| 4. Revision | Shade adjusted and re-dipped if needed | 5–10 working days per round |
| 5. Bulk approval | The approved dip is sealed and used as the bulk reference | 1 day |
| 6. Bulk dyeing | Fabric is dyed to the approved recipe | 10–20 working days |

Two rounds of lab dipping is normal. Plan 2–4 weeks for colour approval before production, and remember that the lab dip is produced on a small scale — bulk dyeing always introduces some variation, which is why the tolerance matters.

## 3. Delta E: the tolerance that protects you

| Delta E | Visual difference | Typical verdict |
| ------- | ----------------- | --------------- |
| Under 1.0 | Not distinguishable to an untrained eye | Excellent match |
| 1.0–1.5 | Visible on close inspection under controlled light | Acceptable for brand colours |
| 1.5–2.0 | Noticeable side by side | Acceptable for general workwear |
| 2.0–3.0 | Clearly different side by side | Reject for branded programmes |
| Above 3.0 | Different colour | Reject |

Specify the tolerance and the measurement method in the purchase order. Without it, "close enough" becomes a judgement call at delivery, and judgement calls go against the buyer.

## 4. Why the same code dyes differently

| Factor | Effect on the final shade | How to manage it |
| ------ | ------------------------- | ---------------- |
| Fibre type | Cotton, polyester and blends dye differently from one recipe | Approve a dip on the actual fabric, not a substitute |
| Fabric construction | Twill, pique and mesh reflect light differently | Compared side by side, the same dye reads differently |
| Dye lot | Batch-to-batch variation in the dyebath | Keep a retained sample; expect DE 1.0–2.0 between lots |
| Finish and coating | Water repellency, FR treatment and calendering shift the shade | Approve the dip on finished fabric |
| Yarn source | Different mills use different raw fibres | Lock the fabric supplier for repeat programmes |

## 5. Cost and minimums for custom colour

| Item | Typical cost or minimum | Notes |
| ---- | ----------------------- | ----- |
| Lab dip | $50–150 per colour | Often credited against the bulk order |
| Custom dyeing uplift | 5–12% on garment cost | Higher on technical fabrics |
| Minimum per colour | 300–1,000 pieces | Driven by the mill's dye-bath minimum |
| Minimum fabric quantity | 300–500 kg typically | Lower for some stock fabrics |
| Second lab dip round | $50–150 | Budget for at least one revision |
| Re-dyeing a rejected lot | Full fabric cost | The reason tolerance matters commercially |

## 6. Metamerism: the same colour under different lights

Metamerism is when two colours match under one light source and differ under another. It is the most common source of "this does not match" complaints on programmes that were technically correct.

| Light source | Where it applies | What to check |
| ------------ | ---------------- | ------------- |
| D65 (artificial daylight) | The standard for colour approval | Primary approval light |
| TL84 / F11 (fluorescent) | Offices, warehouses, retail | Check how the colour reads indoors |
| Horizon / incandescent | Evening light | Warm shifts |
| Outdoor daylight | Site work, daylight inspection | Slight shade differences are visible but acceptable |

Approve the lab dip under D65, then check it under the fluorescent light the workforce actually works in. A colour that passes D65 and fails TL84 will still generate complaints on site.

## 7. Matching colour across garment components

| Component | Who matches it | Practical tolerance |
| --------- | -------------- | ------------------- |
| Shell fabric and pocketing | Mill and garment factory | DE 1.5 or better |
| Fabric and zip tape | Trim supplier | DE 2.0, often impossible to match precisely on textile zips |
| Fabric and reflective tape | Tape supplier | Not colour-matched; tape meets its own standard |
| Fabric and embroidery thread | Thread supplier | Closest thread reference; perfect matches are rare |
| Fabric and printed logo | Printer | DE 2.0 acceptable; inks sit on the surface and read differently |

## 8. Colour fastness: the requirement behind the match

| Test | Typical requirement | Why it matters |
| ---- | ------------------- | -------------- |
| Washing fastness | Grade 4 or better | Fading after repeated industrial washing |
| Light fastness | Grade 5–6 for outdoor workwear | UV exposure on site |
| Rubbing fastness | Grade 4 wet and dry | Transfer onto skin and other garments |
| Perspiration fastness | Grade 4 | Comfort and hygiene |
| Chlorine fastness | Grade 3–4 where bleach is used | Food processing and healthcare programmes |

A colour that matches perfectly on delivery and fades to a different shade after twenty washes has not been matched at all. Ask for the fastness grades with the lab dip approval.

## 9. Matching decoration colours

| Method | Reference to give | Expected accuracy |
| ------ | ----------------- | ----------------- |
| Screen print | Pantone PMS C with a fabric print trial | DE 2.0 typical; ink reads differently on fabric than on paper |
| Embroidery | Thread colour card code, closest match to TCX | Closest available thread; exact match rarely possible |
| Heat transfer | Digital colour profile plus a physical proof | Good; always approve a pressed sample |
| Reflective tape print | Tape-compatible ink references | Limited palette; confirm with the tape supplier |

## 10. The approval workflow that prevents disputes

- Send the reference as a TCX code plus a physical swatch where possible.
- Request two or three lab dip options and choose one, rather than asking for a single "correct" dip.
- Approve under D65 and check under the working light.
- Sign and date two copies of the approved dip: one for the mill, one sealed in your file.
- Record the tolerance, the light source and the fastness requirements on the purchase order.
- Compare the bulk fabric against the sealed dip before cutting, not after.
- Keep the sealed dip for the life of the programme — it is the only defence against a drift in shade next season.

## 11. Common mistakes

- **Sending a PMS C reference for fabric**, then wondering why the dye does not match.
- **Approving colour from a screen or a photo.** Neither is a colour standard.
- **Omitting the Delta E tolerance** from the specification.
- **Forgetting metamerism** and checking only under office light.
- **Not keeping a sealed retained sample**, which makes next season's match unverifiable.
- **Approving on the lab dip but not checking the finished, coated fabric**, where the shade shifts.

## 12. Frequently asked questions

### What does Pantone TCX mean for workwear?

TCX is the Pantone textile cotton standard used for fabric and garment colour matching. It is the reference you give a mill, rather than the paper-based TPG or the print-based PMS C standard.

### What is an acceptable Delta E for colour matching?

Civil 1.5 or better for brand colours and 2.0 for general workwear. Above 2.0 the difference becomes obvious side by side and is usually rejected for branded programmes.

### How long does colour matching take?

Five to ten working days per lab dip round, with two rounds common, so plan two to four weeks for approval before bulk production starts.

### How much does a custom colour cost?

A lab dip costs US$50–150 per colour, and custom dyeing adds 5–12% to the garment cost, with a minimum of 300–1,000 pieces per colour because of the mill's dye-bath minimum.

### Why does my reorder not match the first order?

Dye lots vary. Even with the same recipe, expect a Delta E of about 1.0–2.0 between lots, which is why a sealed retained sample from the first approved lot should be kept and compared.

### Can you guarantee an exact Pantone match?

No manufacturer can guarantee a perfect match, because dyeing depends on fibre, construction, finish and dyebath conditions. What can be guaranteed is a match within an agreed tolerance under an agreed light source.

### What is metamerism and why does it matter?

It is when two colours match under one light and differ under another. Approve under D65 and also check under the fluorescent lighting used in the workplace to avoid complaints.

### How do we match embroidery thread to a fabric colour?

Use a thread colour card to find the closest reference and approve a physical embroidered sample. Thread rarely matches a dyed fabric exactly, so the closest match must be agreed visually in advance.
