Dear Aditya and Hans,
I'm not so sure about it being a bug in pgfplots. I played a little and encountered the following.
As Aditya pointed out, these (probably used for tracing) colors are defined in such a way that they don't go via the context resolver. As these (few) colors are basically x windows colors, you can start your document with: \usecolors[xwi] which will set the context colors differently.
\usemodule[tikz] \starttext
% Original gray \blackrule[color=gray,width=1cm,height=1pt]
\starttikzpicture \draw[gray,line width=1pt] (0,0) -- (1,0); \stoptikzpicture
% New colors \definecolor[gray][s=0.5] \unprotect \pgfutil@definecolor{tikzgray}{gray}{0.5} \protect
% Now ConTeXt's gray = tikzgray \blackrule[color=gray,width=1cm,height=1pt]
How is that supposed to work? Context will not inherit colors from tikz, the most you can expect is the reverse: tikz using context color definitions.
\starttikzpicture \draw[tikzgray,line width=1pt] (0,0) -- (1,0); \stoptikzpicture
% Inside TikZ gray is still off \starttikzpicture \draw[gray,line width=1pt] (0,0) -- (1,0); \stoptikzpicture
\stoptext
Cheers, Henri

Dear Hans,
thanks for your reply. Indeed there are color definitions in `pgfutil-context.def`. However, they are commented out with the message

If I add
> \csname pgfutil@definecolor\endcsname{gray}{gray}{0.5}
to my document the gray shows up fine. So that's for sure a feasible workaround.
Can you comment on the phrase »no need for x colors (users can load it if needed)«? I'm not quite sure what it means and it suggests that there exists a proper solution to my color problem.
normally you want the same colors in tikz images as in context so then defining them in tikz is creating incompatibilities (your case is the reverse and a-typical)
However, without such redefinitions, tikz does not understand ConTeXt colors. I use a similar workaround in my documents as well.
I have no clue what you mean.
\definecolor[red][g=1]
\startTEXpage \starttikzpicture \fill[red] (0,0) circle (1cm); \stoptikzpicture \stopTEXpage
works ok here and gives green. So, one can collect a list of colors defined in tikz in a colo-imp-tikz.mkiv and load that one if needed.
I guess it is a bug with pgfplots rather than tikz (which also means that it may be easier to pursuade pgfplot maintainers to use low level tikz interface, since tikz is already playing nice with context).
\usemodule[tikz,pgfplots] \definecolor[red][g=1]
\startmode[bug] \unprotect \pgfutil@definecolor{red} {rgb} {0,1,0} \protect \stopmode
\starttext \startTEXpage \starttikzpicture \startaxis \addplot[color=red] coordinates { (0,0) (1,1) }; \stopaxis \stoptikzpicture \stopTEXpage \stoptext
