What is Delta E (ΔE)?

Delta E is the standard measure of how different two colors look to the human eye, rather than how far apart their hex codes happen to be. It runs from 0, an exact match, to 100, the largest possible difference — so the lower the Delta E, the closer the match. The match percentage shown on each color below is simply 100% minus its ΔE.

ΔE 0

Identical – an exact match

ΔE under 1

Not perceptible; the eye cannot separate them

ΔE 1 – 2

Perceptible only on close, side-by-side inspection

ΔE 2 – 10

Perceptible at a glance

ΔE over 10

Reads as a different color altogether
