You can use \definecolor[mycolor][.5(red,green)] in the current beta,
but I wonder if \color[0.5(red,green)] makes much sense as that would
complicate (and definitely slow down) color switching. But, as Aditya
pointer out you can use {\colored[0.5(green)]test} already. I don't want
to get away too much from the principle of defining colors using names.

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?
PS I've tried using spot colors in context, but that doesn't seem to
work:
\definespotcolor[mycolor][red][p=.1]

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.

OK, thanks. Last question then: is there a way to redefine standard
colors? Something like:
\redefinecolor[red][r=0,g=1,b=0]

TikZ to allow running it under MKIV at all), but works fine in ConTeXt

\usemodule[tikz]
\starttext
\starttikzpicture
\node[circle,ball color=red!10] (a) at (0,0,0) {$p_x$};
