Seeking some tuts

Hey all,

I used to have a ton of good coloring tutorials but I lost all my bookmarks and thus, all my tuts. :( I'm looking for a good tutorial that makes the red in an image stand out. I think you know what I'm talking about. If not I can try to post an example. Anyway I'd appreciate it if someone could link me to a tutorial like that they might already have in their bookmarks/LJ memories/etc.

Thanks in advance!
