Hi Hans

sorry to ask again. But the different color handling between
context-version before 2015.04.14 00:54 and
context-version 2015.04.14 00:54 is remarkable and annoying.

See attached pdf-documents. Both have exactly the same source:

\usemodule[tikz]
\setupbodyfont[40pt]
\starttext
\definecolor[mycola][c=0.23,m=0.58,y=0.88,k=0.45]
\definecolor[mycolb][c=0.115,m=0.29,y=0.44,k=0.225]
\definecolor[mycolc][c=0.055,m=0.145,y=0.22,k=0.1125]

\starttikzpicture
\node[fill=mycola,rectangle, minimum height=4cm,minimum
width=2cm,anchor=south west] {\startcolor[mycola]T\stopcolor};
\node[fill=mycolb,rectangle, minimum height=4cm,minimum
width=2cm,anchor=south west] at (2,0) {\startcolor[mycolb]T\stopcolor};
\node[fill=mycolc,rectangle, minimum height=4cm,minimum
width=2cm,anchor=south west] at (4,0) {\startcolor[mycolc]T\stopcolor};
\stoptikzpicture
\stoptext

I write in each box the letter T with exactly the same color as the
underlying box. Textcolor is set using context, fill color of the box is
set using tikz.

old.pdf shows the correct color handling. The letter T has exactly the
same color as the box and therefore disappears.

With newest beta (new.pdf) the letter T is visible.

Must I now stay with an old beta or can this "bug" be fixed? Perhaps
it's a bug in tikz...

i found out that it relates to the lack of gray support (which in fact seems to be rgb support)

so the next beta might work ok for you (no upload yet)
