I haven't made a tutorial yet, so I thought it was about time to make one =P
All credits for textures can be found in my resources.
»Color Balance - +8, +12, -10
»Set this texture on top of the color balance layer to Multiply, 100%.
»I moved around the model so she could be appearing more on the icon with this texture.
»Set this texture on top of the other texture to Multiply, 64%, or however you want to.
»I erased the parts of that texture that covered the model.
»Finally, set this light texture on top of the texture just placed to Screen, 100%, or however you want to.
»I moved the texture to the right a little to keep just that part showing on the icon.
Voila! You are finished!
I hope some of you found this tutorial helpful! Keep in mind that this type of coloring might not work on all icons. Please comment if you found this usefull or just to show me any icons you made based on this tutorial, and feel free to request any tutorials of any icons I made. =]
