Dear All,
I am puzzled about the chromaticity coordinates of the colorants in
different profiles. For example, on numerous websites the chromaticity
coordinates of the sRGB profile is described as:
x y
Red 0.64 0.33
Green 0.30 0.60
Blue 0.15 0.06
However, if I use the cmsTakeColorants function (but the same result is
obtained with the ICC profile inspector), I get
x y
Red 0.6485 0.3309
Green 0.3212 0.5978
Blue 0.1559 0.0660
Also when I look at other standard profiles I get decrepancies, especially
in the x-coordinate of Green. Does anyone know why this is? Does it have
to do with the white point or the iluminant data???
Kind regards,
Gerard
