Ahoi!

Is it possible to "colorize" bitmap or greyscale images with ConTeXt?

e.g. I use a bitmap logo that should show exactly the same color as defined 
for backgrounds. If I define the "same" color with PhotoShop it looks 
slightly different. Further I'd like to place it white on color.

I know that at least PDF 1.4 enables such with "DeviceN" colorspaces,
but I found no way to do it with ConTeXt.
It should as easy as in other functions to assign foreground and background 
color, maybe even transparency?

Grüßlis vom Hraban!
