Brighter eyes as of v0.2.6b

From v0.2.6b, the eyes should be slightly brighter at the edges of the sclera, since it is a little difficult to see eye colors, especially in bright and glow-ey environments. I really do like the more realistic and detailed irises from this update, but the colors, unless they are at the highest hue, look somewhat dull and greyscale-ish. Sorry for sounding nit-picky.
