Alright so we're gonna start out with our image. I chose a picture of Megan Fox from the Transformers: Revenge Of The Fallen press conference. Crop your image and do whatever else you need to do to it. I didn't need to do anything to it.



01. Layer -> New Adjustment Layer -> Curves

RGB:
Input - 125
Output - 145

This has the same effect as a Screen layer but it looks a lot better in my opinion. This'll brighten up our base a wee bit.



02. Layer -> New Fill Layer

Okay now we're gonna fill this layer with a light brown color. I chose #d6bfaa. We're gonna set this color fill layer to soft light at around 45% opacity. I would play with your settings so it fits your icon needs.



Megan's getting a wee bit darker now.

03. Layer -> New Fill Layer

For this step we're gonna fill this with a very dark brown color. I chose #390507. Set this layer to Exclusion at around 50% opacity.



Bigger difference now.

04. Layer -> New Fill Layer

Alright now we're gonna fill this layer with a Slytherin Green color. I chose #5d6f5e. We're gonna set this layer to Exclusion. Don't freak out! Lower your opacity to around 20%.



Oh hai Megan. You're looking darker.

05. Layer -> New Fill Layer
For this layer, we're gonna fill it with a burnt orange color. I chose #dc793a. This layer's gonna be set to Color Burn. Again don't freak out if your icon looks weird! Lower the opacity to around 20%.



Now that we've basically made Megan pretty dark, let's lighten up this icon!

Layer -> New Adjustment Layer -> Color Balance

PLAY WITH THESE SETTINGS. They don't always work!

Shadows: 25, 2, -16
Highlights: -35, 0, 50



& here's our final result! Notice how this tutorial gave a nice coloring without using Selective Coloring.
