Colour is the trim attribute most likely to go wrong and the hardest to settle after the fact. Written communication covers how to state the requirement; this article covers the other half of the process: who decides that a colour passes, under which conditions that decision is made, how it is recorded, and what happens when one batch drifts. Settle those three points and most colour disputes disappear.
1. The Three Documents Colour Approval Must Leave Behind
Colour approval is not a glance and a nod; it turns a subjective judgement into archived objects and records. Miss any one of the three and the argument cannot be settled:
- Shade card confirmation: fixes the reference, tolerance, viewing light, material and process in writing as an annex to the order. Close to navy is not a standard.
- Dyed sample: a swatch made with the real material and the real process — paper grammage and lamination, yarn reference, ink type all matching bulk. A digital proof shows layout, not colour.
- Sealed first article: the physical standard from the first approved run, signed and stamped by both sides. Every later batch is compared against it as an object, not against a screen.
2. Viewing Conditions: The Five Variables That Break a Colour Check
The same swatch can read as a different colour under different conditions. These five variables are the most often overlooked — and the ones that produce two sides talking past each other:
| Variable | What usually goes wrong | Recommended practice |
|---|---|---|
| Light source | Judging under office lighting or on a phone screen | Agree a D65 or TL84 light box; if daylight is used, state overcast versus direct sun |
| Angle and distance | Looking at an angle, or holding the swatch right up to the eye | View at roughly 45 degrees from 30–40 cm, with standard and candidate side by side on the same plane |
| Background | Laying samples on a coloured or patterned surface | Use a neutral grey background; pair dark shades with grey or white card so surrounding colour cannot influence the eye |
| Comparability | Comparing thin paper with thick, or uncoated with laminated | Only two samples matching in material, thickness, lamination and finishing may be compared |
| Observer | One person decides with a single glance | At least two reviewers; exclude anyone with impaired colour vision; back critical shades with instrument readings |
3. How Numbers and Eyes Work Together
A numeric index such as ΔE makes disputes simpler, but applied to the wrong case it creates new ones. It suits comparison within one material and one process; across materials — paper against fabric, printing against dyed yarn — the number means little and the physical standard still rules.
- The eye is more sensitive in dark and highly saturated shades, so tolerances usually tighten: the same ΔE is far more visible on a small dark patch.
- Fluorescent and metallic finishes — foil, gold and silver inks — are hard for a standard spectrophotometer to read reliably, so the sealed standard plus a fixed light source governs.
- Woven labels vary with the yarn lot; care labels and hang tags shift with substrate ink absorption and lamination. Write the tolerance per category in the order — never one figure for all.
4. Batch Release: Who Signs, What It Says, What Is Kept
- Before each batch ships or is received, compare it physically against the sealed first article under the same agreed conditions, and record date, batch number and who judged.
- A release note should carry at least: category and specification, batch number and quantity, the sealed standard reference used, the verdict, and any remark on anomalies.
- Retain physical samples at the agreed rate for the agreed period as evidence for later disputes, with the retention ID matching the release note.
- Out-of-tolerance lots go through a written deviation, not a verbal pass: the producing side states the extent and impact, the receiving side agrees in writing, both file it.
