Thank you! Funnily, I was trying to imitate the colorings on your Garrus icons because I really liked how you made the colors stand out but umm, I used a lot of selective coloring and color balance layers, a color balance layer and depending on the base, I'd sharpen it and fiddle around with a duplicated screen or color dodge layer, and play with the hue/saturation to make the colors stand out or mess around with curves so the base's natural lighting might be better.
