Compiling the following example (with xelatex or lualatex), I would expect to get violet letters abc:
\documentclass{article}
\usepackage{xcolor}
\usepackage{fontspec}
\setmainfont{Verdana}
\begin{document}
\color{violet}abc
\end{document}
However the result are black letters. Using \fontspec[Color=violet]{Verdana}abc, I get violet letters as expected. However I do not know how to change color in math mode. Further it breaks automatic coloring of TikZ nodes.
Is this by design, or is it a bug (in either xcolor or fontspec). Is there a workaround? How do I change math colors?
