Fun fact: sRGB also has a non-black black point that is (fortunately) virtually ignored by everyone.
- devit 7y agoSource? As far as I can tell in XYZ black is (0,0,0) and the only sRGB value that maps to that is (0,0,0)
- klodolph 7y agoThis is incorrect. If sRGB (1,1,1) is XYZ (1,1,1), then sRGB (0,0,0) is XYZ (0.0025,0.0025,0.0025). Or if you are using absolute XYZ values, sRGB (0,0,0) is XYZ (0.1901,0.2,0.2178).
- klodolph 7y agoThe sRGB black point just means that (0,0,0) is assumed to have a luminance of 0.2 cd/m^2, because your screen reflects ambient light and other factors. Ignoring it will give you nonsensical values when you try to do conversions into other color spaces or when you try to do color comparisons.
