Perceptually uniform color space designed for measuring color differences. Overview CIE LAB (also written as CIELAB or Lab*) is designed to be perceptually uniform, meaning that equal distances in LAB space correspond to roughly equal perceived color differences. This makes it ideal for: Color difference calculations …

Quantifying perceptual differences between colors using Delta E metrics. Overview Color difference formulas quantify how different two colors appear to the human eye. They're essential for: Quality control in manufacturing Color matching and reproduction Perceptual image processing Color tolerance specifications Delta …
