Actually, as I pointed out earlier, it's indexed (256-color palletized) PNGs that cause RGB color definitions to be added to FM. As John Hogan pointed out, most PNGs are 24-bit (millions of colors) these days, which doesn't cause the problem and is not that much bigger, file-size-wise. 

Since PNG is lossless, free of artifacts, and even (according to Wikipedia) renders gradients more accurately than JPEG, I can't imagine why anyone would use the latter for screenshots.
