Better than Lab? Gamut reduction CIE Lab & OKLab - Chris Lilley (W3C)

Описание к видео Better than Lab? Gamut reduction CIE Lab & OKLab - Chris Lilley (W3C)

Colors which are outside the gamut of the display device need to be mapped so that they are within the gamut. Although an industry standard for decades, CIE Lab is known to exhibit limitations such as over-estimating color difference with high-chroma colors (even with deltaE 2000), and a hue non-linearity in the blue-purple region. This talk reports on investigation of a newer opponent color space for gamut reduction of individual colors. This will inform browser implementations of gamut reduction, particularly if ICC profiles are not being used.
