coloring.

Hi everyone! So, I found this batch of icons I'm positive uses the same coloring and I've seen it everywhere! It's like a simple, sudle coloring that works on like EVERYTHING! I was wondering if anyone knew any good tutorials for it. I know it definately uses selective coloring but otherwise I have no clue. So if ayone here could help that would be great. Another girl asked the maker and she has yet to reply (she asked today) and I'm very impatient and I'm afriad I'll lose the url so any help would be great; thanks much!
