Last post got messed up, here's what I ment to say: I'm not exactly sure what your method of reading the image in is (I've never done any images in Perl yet) but it seemed to me that the color should be encoded in hex in the image file. If this is true you can just have the Perl script generate a whole ton of really ugly HTML with. Just have the perl script put <font color="#color's_hex_value">. I'm pretty sure that will work.

Just the ideas off the top of my head ...
