I was thinking about the eye color of characters throughout the KH universe.
Yellow seems to indicate a deep rooted darkness within the person. Only those people who have been corrupted by Xehanort, or the darkness in general, have yellow eyes. Xehanort (Old and Young), Xemnas, Ansem SoD, Braig, Saix and Vanitas all had yellow eyes.
Some other characters, notably Axel and possibly Vexen, have lime/aqua green eyes, indicating a "neutral" phase of light and darkness. They're neither here nor there. They could go either way.
Most other characters in the Kingdom Hearts universe have blue eyes; they are people of light.
Does this mean that there are varying degrees of darkness that a person could hold? Go off of the color spectrum: ROY G BIV. By extension, would it be possible for a person to have red eyes of pure darkness? Or violet eyes of absolute light?
What do you think?
