I always wanted to make a tutorial... so here one is.
I'm using Photoshop CS3.
going from
to
1. Duplicate your base layer and set to screen 64%.
2. New Layer > Selective Color
Red - -90, 0, +55, 0
Neutrals - +27, 0, 0, 0
3. New Layer > Solid Color - Set to Exclusion - use #000458
4. New Layer > Curves
RGB - First point - Output 41, Input 53 - Second Point - Output - 187, Input - 151
Red - First point - Output 44, Input 30 - Second Point - Output - 199, Input - 176
Blue - First point - Output 37, Input 51 - Second Point - Output - 185, Input - 192
5. New Layer > Fill part way with black, move down so that it only takes up the bottom of your avatar. Move the layer down below your color layers to give it a blue-ish color instead of plain black.
6. Font - Violation, Color - # f9f0ab
I hope it works for you. If I screwed something up... let me know so I can fix it.
