hehe... you could try just doing wholesale changes on a button
tweaking the algorithm each time until it looked like you want :)
You could also maybe do a nearest neighbor for one or two pixels
in every direction, to see if you are near a pure blue.
But the easiest would probably be to

Thanks everyone for your suggestions.
Using one of the libraries recommended, I believe I can walk the
directory, load each gif image and then loop through each pixel,
changing all solid colors from e.g. blue (0,0,255) to green
Did you look in the Perl Graphics book yet?
I did check out the perl graphics book examples, and none of them
looked relevant, but... I'm going to sign up for Safari and read
through it. Looks like I get two weeks free, so I can do the book due
diligence pretty quickly. Thanks

As for changing image colors, you could do that with imlib2
as well... though maybe pixel by pixel. The probalem you may run
into is if they have anti-aliased text, which will make wholesale
color-swapping difficult.
Thanks everyone for your suggestions.
Using one
Well... I have scripts set up to do button/tab etc
generation of my company's web graphics using all perl.
I create the images using Imlib2 and xml templates.
I really doubt I could share the code with you, but I
could probably help you along, and even give you my slightly
enhanced version
