Ya'know, this is interesting to me. I'm fairly bad at gauging color balance. I can see the differences between two pictures that have had their color balance adjusted, but I can't pick one or the other as being apparently better. As a matter of fact I have a lot of difficulty in dealing with any sort of subtlety. Adjusting contrast, brightness, whatever. Yet apparently I'm good at perceiving differences.
