Frequently Asked Questions
What is Delta E (ΔE)?
Delta E is a metric used to quantify the difference between two colors. It measures how much a color deviates from a reference color, with lower values indicating closer matches and higher values indicating larger differences.
Which Delta E formula should I use?
CIEDE2000 is the most modern and accurate formula, designed to match human color perception. CIE76 is simpler but less precise, while CIE94 is often used in industrial graphics.
