Delta e (the total color difference) is based on delta l*, delta a*, and delta b* color values, all of which provide a complete numerical descriptor of the color in a rectangular coordinate system. Use the form below to convert color data across different color standards and color spaces (rgb, cmyk, l*ab, l*ch, l*uv, hunter, xyz etc.). The l* (from l*a*b*)is perceptual lightness, approximating the human eye's gamma of photopic vision.the intention is to be perceptually uniform.
