Somehow, I don't think that "Ooh, aaah" is the right sound-effect for this power. For a lot of people, it would more along the lines of, "Duuuuuuuude. The colors. They're like, daaaaaancing. Far out, man." And then, once the spell-power fades, they're going to sound more like, "Life is pain."
By the way, are augmentations 3 and 4 cumulative?
