[[Graphics]] Coloring Techniques- Share/Request

First off, I'm sorry if this is in the wrong place/not nessesary, but after searching very thourouly on Google, I really needed this as a place to improve my graphics.
This is basically a place to share anything you to color your graphics.
This is NOT a place for .psd files, but actual actions you take whilst making the graphics.
Please tell us which program you use to do the effects, and whether or not it would be able to be used in other programs.
When submitting an effect, please use the form below--
Program:
Translateable?:
User:
Technique:
You can also post a graphic/link to one, either asking what others think would be a good coloring effect to add, or posting one already colored, asking if anyone knows how to color it that particular way.

I'll add all the effects here to the first post so you don't have to scroll through any posts. ^_^
