I don't know about Context, but you can color separate arbitrary dvi
files via dvips: use a header file colorsep.pro which redefines colors
for each of the separation plates. This file is included on the TeXLive 
cd and its use it documented in the LaTeX Graphics Companion. I don't 
know whether it can be made to work with dvipsone. It doesn't work with 
bitmapped rgb images but should work with bitmapped
cmyk images. I have used this for some real work.

Or you can separate arbitrary PostScript level 1 with
aurora, which can be obtained from the author's home page:
www.cs.adfa.edu.au/~gfreeman/index.html. This one can handle rgb images.
I believe you use it by simply prepending aurora.pro and a
plate-specific header file to your PostScript file.
