In the following MWE I get a red square, but I want it to be gray, as in the also provided LaTeX-document:

```tex

% ConTeXt MWE

\setupcolors[state=stop]

\usemodule[tikz]

\starttext

\tikz{\draw[color=red,fill] (0,0) rectangle (1,1)}

\stoptext

```

```

% LaTeX-document wich does what I want

\PassOptionsToPackage{gray}{xcolor}

\documentclass{article}

\usepackage{tikz}

\begin{document}

\tikz{\draw[color=red,fill] (0,0) rectangle (1,1)}

\end{document}
