Question 1

What is Delta E (ΔE)?

Accepted Answer

Delta E is a standard measurement defined by the International Commission on Illumination (CIE) to quantify the difference between two colors, accounting for the non-linear perception of the human eye.

Question 2

What is the difference between CIEDE2000 and CIE76?

Accepted Answer

CIE76 was the first formula (standard Euclidean distance), while CIEDE2000 is the latest and most sophisticated standard. It compensates for perception issues in the blue-purple region and aligns best with actual human vision. This tool uniquely implements the highly accurate CIEDE2000 formula.

Question 3

What do the Delta E values mean?

Accepted Answer

Generally, ΔE < 1 is imperceptible; 1-2 is barely perceptible; 2-10 is a clear difference; >10 represents completely distinct colors.
