There's an analogue to the image operator callec "colorimage" which
takes RGB or CMYK raster data.  You'll find it documented in the
PostScript Language Reference Manual, second edition.  You can also
get the documentation for this operator (it was an extension to the
original design) on the Adobe file server.  Try sending a mail message
to "ps-file-server@adobe.com" with the subject line 
"send Documents/Color_Ext.ps" (or, if you're running unix and have
the btoa software, you could try "send Documents/Color_Ext.ps.Zba"
instead; the smaller, compressed message will have a higher priority
with the file server so you'll likely get it sooner.)

I think you'll find it easiest to use if you reformat your data to be
interleaved either by pixel (RGBRGBRGB) or by scanline (1 line of R,
one line of G, one line of B, one line of R, etc.)

Hope that helps.
