Elk is right that green is too natural of a color to represent something as supernatural as magic. But blue also feels very natural to me as well, it's just not as earthly as green.

I always think of magic as purple.
I guess it depends where you think that magic comes from within the human body.
I associate magic with the power of the mind, but maybe that is just me.
But every time that I have used magic in real life it has manifested as a purple glow around my hands.
