Hi,

The following example works in MkII and it works in TeX Live 2014, but it fails with the latest beta (it draws a black rectangle instead of using the defined colour):

\usemodule[tikz] \starttext \definecolor[mycol][r=0.9,g=0.8,b=0.8] \starttikzpicture \fill[mycol] (0, 0) rectangle (2,4); \stoptikzpicture \stoptext

It would be really nice to fix this in time for TeX Live 2015.

Hm, i'm a bit puzzled why some suggested patched are nto in the distribution. Anyway, attached a more modern variant you need a beta that i just uploaded because i found out that when tijz predefines some mixed colors it assumes rgb color space your example then runs ok here Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Hi Hans is it correct, that with the new beta one can just use rgb-colors using tikz or is there a bug preventing the usage of cmyk-colors as it used to work before? Thanks! Christian PS.: See mail below for MWE showing false cmyk colors in tikz. 2015-04-14 11:54 GMT+02:00 Christian Prim :

Thanks Hans for clarification. But even with simple context color models (that worked before) I get other colors.

MWE:

\usemodule[tikz] \setupbodyfont[40pt] \starttext \definecolor[mycol][c=0.23,m=0.58,y=0.88,k=0.45] \definecolor[mycol_h][c=0.115,m=0.29,y=0.44,k=0.225] \definecolor[mycol_q][c=0.055,m=0.145,y=0.22,k=0.1125] \startcolor[mycol] {\bfa •••••••• Test} \stopcolor

\starttikzpicture \fill[mycol] (0, 0) rectangle (2,4); \fill[mycol_h] (2, 0) rectangle ++(2,4); \fill[mycol_q] (4, 0) rectangle ++(2,4); \stoptikzpicture \stoptext

I'm not so familiar with metafun, so I couldn't do the rectangle with metafun (the different colors between context/metafun and tikz would certainly be better visible so). But the bullet shows, that the text color isn't the same as the tikz-figure. But they should as they are identical. Something must have changed in color handling.

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... Thanks Christian Am Don, 16.

cmyk should work ok but afaik tikz assumes rgb in some cases so that prohibits that we can do automatic conversion tp other color spaces at he context end

...

Thanks!

Hi Hans I don't know if the latest beta already has the new code. But I can confirm, that there is still a difference between tikz-colors and context/metafun colors. TikZ translates c=1,m=1 in (native) RGB, that is b=1, which is in some way correct. ConTeXt translates c=1,m=1 in something I couldn't really define (perhaps sRGB or some other color profile) r=0.183... g=0.191... b=0.574... or in Web-Hex: #2e3092 or back to cmyk: c=.68, m=.67,k=.43 (which is blue with some key-value compared to TikZ with k=0) So I think that TikZ and ConTeXt don't use the same color profile.... Hope it could help somewhat to solve my problem.

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)

your example works ok here (with the tikz def file i made last week)

i also made

\setupcolors[cmyk=no] \setupcolors[rgb=no] \setupcolors[cmyk=no,rgb=no] \setupcolors[state=stop]

working (nothing needed in tikz as the code that interfaces to it does that) which will be in the next beta
