I made a workaround in that way, but it's still a bug ...
I have no clue what the ! does apart from defining a color red at 10%
but I do know that context ignores it.

The '!' is actually pretty neat, since it allows you to blend colors. By
default, tikz blends colors with white, so
red!10
means mix 10% red with 90% white. This has the advantage that I can take
any color, say
\definecolor[mycolor][r=0.42,g=1.,b=0.2]
and lighten it 50% by just using
mycolor!50
I can also blend two colors together, using
colorA!50!colorB
I'm also pretty sure that context didn't always ignore the exclamation
mark. Is there a way to reverse this behaviour?
I'm pretty sure that I never implemented something using a questionmark.
However, we do have:
\definecolor[red-t] [r=1,t=0.5,a=1]
\definecolor[green-t][g=1,t=0.5,a=1]
\defineintermediatecolor[mycolora][0.5,red,green]
\defineintermediatecolor[mycolorb][0.5,red-t,green-t]
\starttext
test {\mycolora OEPS} test
test {\mycolorb OEPS} test
\stoptext
I could probably support
\definecolor[xxx][0.5(red,green)]
\definecolor[xxx][0.5(red)]
which looks better than this ! and is less likely to conflict with names
as abc! is a rather value color name.
