I have dark brown eyes, i find blues, greens, purples, gold, bronze, orange, yellow, grey and black eyeshadows make my eyes pop. I guess it depends on your skin tone and hair colour though.
I absolutely love wearing blue! And it HAS to be Freshwater LOL. Pop some dark navy blue into the crease (I use a Smashbox colour in Ink...I think it's d/c'd), then some Carbon to smoke it out. Shimmermoss to blend out the dark blue, Crystal Avalanche for a highlight, and BAM.
