Not all the colourspaces are perceptually uniform nor try to be. For example, CIE XYZ is photometrically linear and appropriately so!
- jacobolus 6y agoXYZ does not provide correlates of hue, lightness, brightness, chroma, colorfulness, saturation, blueness–yellowness, redness–greenness, or the like Y = relative luminance, XYZ are tristimulus coordinates, and x, y or u', v' are chromaticity coordinates. These are all physical rather than perceptual quantities.
- roel_v 6y agoI'm a bit lost in the discussion here - is your first line a correction of the GP and you used the > mark 'wrong', or did the GP update his post and is the quote not in there any more?
- raphlinus 6y agoThe first. I should have added "perceptually uniform," kelsolaar is correct.
