CIELAB is basically an attempt to approximate the Munsell renotations with a simple and invertible formula (the Munsell renotations are a lookup table), suitable for implementation on hardware from the 1960s.
- kpil 9y agoCIELAB gives nicer looking gradient with clear colors without brown or gray tones, while keeping the luminosity more or less the same.
- jacobolus 9y agoI’m not sure what you are responding to. “Gives nicer looking gradient” than what? CIELAB is a very simple model, which has been very successful but also has various deficiencies. In particular it specifies a broken method of white point adaptation (this can be swapped out), and involves a nasty blue-purple hue shift at constant CIELAB hue which can have big impacts on images put through a gamut mapping algorithm in CIELAB space, e.g. for printing.
- kpil 9y agoThan HSLuv. HSLuv seems to generate brown/gray intermediate colours when interpolating. CIELAB interpolates through clearer hues. In my opinion that looks nicer on charts such as heat maps, etc, but it might not be a good choice as a general tool.
