TikZ colors in cmyk mode broken

TikZ colors in cmyk mode broken

[Mojca Miklavec]

Dear Hans (and other TikZ gurus),

Here's a small example that fails to compile:

\setupcolors
    [rgb=no,cmyk=yes]
\usemodule
    [tikz]
\starttext
\tikz\shade[shading=ball,ball color=yellow] (0,0) circle (1cm);
\stoptext

Do you have any idea how to fix this?

?

I'm not a tikz guru.

no, but my guess is that tikz doesn't support cmyk in all places
