Hai, question.

Hiya, I just wanted to request some assistance for some tutorial's I'm looking for. When I was looking around a couple of month's ago, I saw some coloring tutorial's. To be more specific, they were how to make certain color's stand out, red for instance. I don't really know how to put this, lol because I'm such an idiot when it comes to things like this! Uhh, well really...I'm looking for that but to be even MORE specific, I saw an icon somewhere. I cant remember who it was, but she had red highlights in her hair and the author had really made them stand out, and the rest of the picture was kind of icy blueish and slightly faded?

Anyway, I really hope you can help.
