[Lcms-user] XYZ values of colorants seem different?

[<Wi...@ni...>]

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
