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 …

Device-independent color space based on human vision tristimulus values. Overview CIE XYZ is the foundation of colorimetry. It's based on how the human eye perceives color through three types of cone cells (L, M, S). XYZ values are device-independent and serve as an intermediate space for most color conversions. RGB to …
