Using PS CS2, but it's translateable :]. Pretty simple too!
1. Crop your base to 100 x 100 pixels. You can sharpen it if you wish.
2. Duplicate the base. Set it to screen. Mine was left at 100%, but you can change it until it looks good (and you can go back at the end).
3. New fill layer. Fill with #AEDCFF or this. Set to colour burn 100%.
4. Make a New Adjustment layer > Curves. Put in these settings:
And with that, you're done. The colouring is simple, but I like it. I'd love to see what you guys get, and I love comments!
Also, I'll help if anyone needs it :]
