A combination of red and gold eyeshadow is great for emphasizing green eyes - this is because red and gold are complementary colors to green. For the base, apply a clear or skin-colored base to the entire eye area. Use a highlight base just beneath your eyebrows. Blend it in. Use a black liquid base on the upper eyelid. For eyeshadow, start off with a shimmery gold by putting it in the inner corners of the upper lid. Take your red and start off slightly in the middle of your eye, where you left off with the gold. Cover the entire lid and make sure to blend it in. Use a darker red for the outer corner. Add mascara or eyeliner to the lower lid and you're all set.
