Dear Hans, thanks for your reply. Indeed there are color definitions in `pgfutil-context.def`. However, they are commented out with the message
% no need for x colors (users can load it if needed) ... %\pgfutil@definecolor{gray}{gray}{0.5}
If I add
\csname pgfutil@definecolor\endcsname{gray}{gray}{0.5}
to my document the gray shows up fine. So that's for sure a feasible workaround. Can you comment on the phrase »no need for x colors (users can load it if needed)«? I'm not quite sure what it means and it suggests that there exists a proper solution to my color problem. Cheers, Henri On 07/12/2016 02:29 PM, Hans Hagen wrote:

Dear list,
I wanted to draw some nice pictures using TikZ and pgfplots, but then I noticed that the colors of the ticks in my pgfplots graph were unusually bright and it looked very weird. So I set up a test
\usemodule[tikz] \starttext \starttikzpicture \draw[help lines,very thick] (0,0) -- (1,0); \stoptikzpicture
\externalfigure[test-crop] \stoptext
where I produced test-crop.pdf from the following plain TeX sample, which I also typeset with LuaTeX 0.95 (to make sure it's not a LuaTeX regression).
\input luatex85.sty \input tikz \tikzpicture \draw[help lines,very thick] (0,0) -- (1,0); \endtikzpicture \bye
Attached you find the output of the ConTeXt example and you can see that the color of the upper line (the one produced with TikZ inside ConTeXt) has a much brighter color than the one produced with plain TeX.
I'm using ConTeXt MkIV distributed with TL 2016.
How can I adjust the colors in ConTeXt to match the ones produced by plain TeX? I need the adjustment in that direction, because I also have old images produced with plain TeX/LaTeX that I'd like to seamlessly integrate in my ConTeXt documents.
you need to figure out the default definitions in tikz then (i suppose 'help lines' is related to some color)
