To approve a color match, put physical swatches for the cap and shirt side by side under the lighting where the uniform will be worn. Check them again under a second agreed light source before approval.
Spot a mismatch when the light source changes
Two swatches may match under one light source and look different under another. This is called metamerism. D65 and CWF are two light sources you can specify for textile color approval. ACT guidance on color.
D65 represents standardized daylight. CWF stands for cool white fluorescent. If people will wear the caps in a store, record the type of lighting used in the area where you need the colors to match.
If the colors differ under both sources, first check the fabric code, dye lot, and fabric face. For shiny or textured surfaces, align both swatches in the same direction and compare them again from the same angle.
Record the viewing conditions on the approval sheet
| Item to record | How to use it |
|---|---|
| Reference swatches | Keep the approved shirt swatch and cap fabric swatch, with their color codes and dye lots. |
| Lighting | Record the primary and secondary sources and the viewing location. Use each source separately. |
| Swatch placement | Set the face sides next to each other, with the fabric running in the same direction against a neutral background. |
| Results | Record the difference you see under each light source, the approver, and the date. |
| Finished samples | Compare the assembled cap and shirt to check how shape, texture, and sheen affect their appearance. |
TACS workshop note — Keep the approved pair of physical swatches. Use photos to point out where colors differ, and use the retained swatches and approval sheet to repeat the comparison.
Suppose two navy swatches match under store lighting, but the cap looks purple in daylight. The approver can request more samples or record how much variation is acceptable where the uniform will be worn.
Check each lot against the retained swatches
Record the lot code for each cap component. If the order uses several lots, take a representative sample from each. Compare the crown and visor too if they come from different pieces of fabric.
If the contract requires color measurements, agree on the instrument, measurement locations, formula, and tolerance before approval. Apply the same agreed method to the production lots.
