Tikz colors are broken when using anything other than red, blue, or green. I know that colors defined in ConTeXt used to work in Tikz, so perhaps something has changed recently at the TikZ end. @Mojca: The following definitions can go in t-tikz.tex \usemodule[tikz] \define\starttikzpicture {\hbox\bgroup\forcecolorhack\tikzpicture} \define\stoptikzpicture {\endtikzpicture\egroup} \starttext \red{This is red} \qquad \darkred{This is dark red} \starttikzpicture \draw (0,2) node[color=red] {This is red}; \draw (4,2) node[color=darkred] {This is dark red}; \stoptikzpicture \stoptext Aditya
