FAQ
How does scoring work?
Huezle uses Delta E (CIE2000) — a scientific measure of how humans perceive color differences. A score of 0 means a perfect match. You win when your mix is within Delta E ≤ 2 of the target.
What are CMYK cards?
Cyan, Magenta, Yellow, blacK, and White — the five color channels used in subtractive color mixing. Each card adds +25 to its channel. Stack cards to increase intensity.
