Thanks for the very rapid answer.
However, no, neither of the proposed solutions work.
1. Of course, I tried "\pdfimagehicolor=1" without results before posting the
question. (I would NEVER think about asking for help without trying different
possibilities myself...)
2. "\setupcolors[state=start]" was also in my original file, but did not seem
to make a difference, so I posted a most simplified example.
What to do? I would think that there is something wrong with my configuration
(debian/unstable), however pdflatex works just fine.

(P.S. Why would one need to specify \pdfimagehicolor in any case; From a
user's point of view, shouldn't it just work transparently?)

There, fixed that.
That setting could go into the context core, though.

I am always surprised how many people ask a question,
guess the correct answer themselves, but don't actually
attempt to see if it works :-)
Best wishes,

Hi
Does adding \setupcolors[state=start] at the top of the context file help?
Hans, how about enabling colors by default in mkiv?
