Are you compressing right from the timeline, or are you making a master ProRes file first? If you do, check to see that your file looks like what you see in the timeline. You could also check your setting in compressor to see how its handling color space.
Personally, I seldom, if ever, mess with the individual color settings in Compressor. Better to make sure that your master files are the way you want them first, then send them thru compressor.
