My background is in Art/Architecture. I have a Bachelor's degree in Art and I am an avid painter (my medium of choice is acrylics). So, it's actually hard for me not to think of makeup in an "art" way. In my opinion, one of the most asked questions is "what color of eyeshadow will work with my [blank] color eyes". Let's open up that can of worms, shall we?
Taking it a step farther, what does this mean when people say "warm" and "cool" colors. In reality, every color up there can also have warm or cool versions of itself. There are warm blues and cool oranges.
"so, Jeweled Thumb, what if my eyes are green?"
As I said earlier, technically red is on the opposite side of the color wheel. However, using variations of red + the other colors around it will also bring out your eye color (just not as much as wearing red eyeshadow would).
I'm going to display some "swatches" from the Sephora.com website for the brand Make Up Forever (MUFE for short).
First, we have "green eyes":

OR BROWN. See, I'm sure as you all noticed when you were a kid. If you mixed all your paint colors together, you will get brown. So, the darkest shade, has brown and red and probably a little purple thrown in (which is blue and red).
So the shade names I generally suggest for green eyes?
Copper (red + orange + brown) & Peach (red + yellow + white)
I could write pages and pages on this, but I'll stop... for now.
