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
