Camille, Gil Prive posted a set of CMYK colors before:
http://sourceforge.net/mailarchive/message.php?msg_id=2299470 My only comment was that you don't need to add a preceeding underscore to his color names -- you can simply redefine the ones which already exist. set_color _green= [0.00 , 0.53 , 0.22] can be set_color green=[0.00,0.53,0.22] etc. One thing you can do with existing images is use Photoshop's Image->Mode->Convert To Profile option to adjust how the conversion is performed (at least I think that is what it does). I'm not sure Illustrator allow you to control RGB to CMYK conversions as well as Photoshop. The thing to understand is that CMYK is a subset of RGB color space. Many RGB colors simply don't exist in it. Bright green is one of them. RGB to CMYK is lossy, nonlinear, and dependent on the assumptions which are made about the ink colors, blending, and about the paper stock. Warren -- mailto:war...@delanoscientific.com Warren L.

At the moment I'm messing around with the following kind of thing.... set_color cyan2=[0.7, 1.0, 1.0] I need to use a cyan color in a figure but unfortunately this becomes very dark when the resulting ray traced image file is viewed in CMYK mode in illustrator. Greens, especially, seem to suffer in conversion.
