Hi Hans
is it correct, that with the new beta one can just use rgb-colors using
tikz or is there a bug preventing the usage of cmyk-colors as it used to
work before?
cmyk should work ok but afaik tikz assumes rgb in some cases so that
prohibits that we can do automatic conversion tp other color spaces at
he context end
Thanks!
Christian
PS.: See mail below for MWE showing false cmyk colors in tikz.

Thanks Hans for clarification. But even with simple context color
models (that worked before) I get other colors.
MWE:
\usemodule[tikz]
\setupbodyfont[40pt]
\starttext
\definecolor[mycol][c=0.23,m=0.58,y=0.88,k=0.45]
\definecolor[mycol_h][c=0.115,m=0.29,y=0.44,k=0.225]
\definecolor[mycol_q][c=0.055,m=0.145,y=0.22,k=0.1125]
\startcolor[mycol]
{\bfa •••••••• Test}
\stopcolor
\starttikzpicture
\fill[mycol] (0, 0) rectangle (2,4);
\fill[mycol_h] (2, 0) rectangle ++(2,4);
\fill[mycol_q] (4, 0) rectangle ++(2,4);
\stoptikzpicture
\stoptext
I'm not so familiar with metafun, so I couldn't do the rectangle
with metafun (the different colors between context/metafun and tikz
would certainly be better visible so). But the bullet shows, that
the text color isn't the same as the tikz-figure. But they should as
they are identical. Something must have changed in color handling.

Thanks Hans for the fix!
I have noticed, that spotcolors can be used in tikz, but
they are
darker. Is that wanted or a bug?
they will map onto cmyk or rgb depending on definitions ...
don't expect advanced context color models to work with tikz
(but they do work with metafun)
