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. Cheers, Henri
