GD jpg thumbnail - ugly discollored

I have a script that takes uploaded images (jpeg only) and makes proportionate thumbnails etc, and saves them in jpeg (.jpg) format again (default compression of %75 I think) anyway, the thumbnails are UGLY. Beauty of content aside, they are discolored, and usually one predominant color takes over the entire picture so they come looking like off-black and white thumbnails. WHY? And how can I fix this/get around it? This is some extra info.
