Document range of JCh channels

Open clamydo opened this issue 5 years ago • 2 comments

I could not find any documentation of the range of the channels in JCh variant the CICAM02. Or is there no such thing as a range for this values?

Additionally, is there a way to calculate ranges that produce valid SRGB?

Have you figured it out?

The model is not bounded so there is not really a defined range. As to find that of sRGB, you could simply use the primaries and complementary colours to define a volume and compute the CIECAM02 values with that.

RGB = [[0, 0, 0], [1, 0, 0], [0, 1, 0], [0, 0, 1], [1, 1, 0], [0, 1, 1], [1, 0, 1], [1, 1 ,1]]
