Losing the colour red

I ran into a really odd problem. All of a sudden the colour red disappeard from my desktop. Everything that was previously red - the mozilla dragon icon, for instance - turned black. But here's the weird part: I could still watch movies with xine perfectly well. Redheads were still redheads in my dvds. I guess this means it's not a problem with my monitor but rather an X thing. Has anyone seen anything like this before? //Anders -- `When I use a word,' Humpty Dumpty said in rather a scornful tone, `it means just what I choose it to mean -- neither more nor less.'
