How to

How to record a trial
Give the letter, the formulation or lab recipe, and the L*a*b* reading under each light. On save, the ΔE per light, metamerism and verdict are calculated against the lab dip's target colour.

Rules

The customer's yes is per light
Tick "Customer approved" under each light the customer checked. Approval only goes through when every light read has a yes.

Frequently asked questions

What does "changes with the light" mean?
The ΔE was good under one light and bad under another (metamerism): the color the customer approves in daylight may come back later under store light. Prefer an attempt that passes under all three lights.
