Dear List,

I use the latest version of ConTeXt and I have the following MWE:

\usemodule[tikz]
\starttext
  \starttikzpicture
    \node {\color[red]{red}};
    \node[xshift=30] {\color[red]{not red}};
  \stoptikzpicture
\stoptext

Can anybody tell me why the second node is not colored red?

Aside: In LaTeX when using \color{red}{...} this tikzpicture renders
correctly. For LaTeX I use TikZ version 3.0.1a, in ConTeXt it seems to
be version 3.0.1.

Any feedback is welcome.

Regards,
Christoph

Thank you Hans! This workaround does the job.

For those interested: The \zwnj can be prepended automatically to
every node by setting "every node/.add code=\zwnj". The updated MWE
now is:

\usemodule[tikz]
\tikzset{every node/.add code=\zwnj}
\starttext
  \starttikzpicture
    \node {\color[red]{red}};
    \node[xshift=30] {\color[red]{not red}};
  \stoptikzpicture
\stoptext

Cheers,
Christoph
