Different colors in LaTeX and ConTeXt
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

you need to figure out the default definitions in tikz then (i suppose 'help lines' is related to some color) ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
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 Aditya and Hans, I'm not so sure about it being a bug in pgfplots. I played a little and encountered the following.
\usemodule[tikz] \starttext

As Aditya pointed out, these (probably used for tracing) colors are defined in such a way that they don't go via the context resolver. As these (few) colors are basically x windows colors, you can start your document with: \usecolors[xwi] which will set the context colors differently.

How is that supposed to work? Context will not inherit colors from tikz, the most you can expect is the reverse: tikz using context color definitions.

Adding \usecolors[xwi] to the example does not change anything. Looking at base/colo-imp-xwi.mkiv revealed, that it does not alter the way colors are defined, but just defines a huge bunch of additional ones.

I'm very sorry for the confusion. What I did was to adjust ConTeXt's gray to have the same grayscale value as the tikzgray. As is shown below, the redefinition of gray does not propagate to TikZ.

In pgfutil-context.def there is though \let\pgfutil@registergray \pgf@context@registergray So it seems as if gray *should* be propagated from ConTeXt to TikZ, which apparently takes place when loading TikZ. Moving \definecolor[gray][s=0.5] before \usemodule[tikz] shows this behavior. The question is how to keep colors from ConTeXt and TikZ in sync. Cheers, Henri

afaiks it has the same 'gray' as tikz 'gray' and that is what you want
I'm very sorry for the confusion. What I did was to adjust ConTeXt's gray to have the same grayscale value as the tikzgray. As is shown below, the redefinition of gray does not propagate to TikZ.
that is as Aditya mentioned probably due to the fact that some of these built in colors are not using the normal color resolver and there's nothing we can do about (apart from rewriting part of the tikz color interface which is not on my agenda)
So it seems as if gray *should* be propagated from ConTeXt to TikZ, which apparently takes place when loading TikZ. Moving \definecolor[gray][s=0.5] before \usemodule[tikz] shows this behavior.
The question is how to keep colors from ConTeXt and TikZ in sync.
by defining them in your document (at least these 10 or so predefined colors) (you could have similar issues with colors defined in rgb or cmky in one or the other) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
