Protagonist

Matches what I personally know of the history of symbols and consciousness. White, the order and organization of conscious multitudes, created a group mind and a sense of the "objective world". Black, the taste of sacrifice and evil and death, was the evolving sense of action for deliberated benefit, the "argument for evil" as represented by a snake. Red, impulse and instinct itself, is the first human acting in paradise, sans shame or worry, and leading to rebellion. Artifice, the creation of tools and the mastery of material, is associated with Cain and Vulcan, the first artisans. Green, the appeal to and participation in nature, is the first in a long line of human-created institutions, in the form of might makes right. Blue, the formalized and structured thought that came from literary and rhetorical traditions, made words (and "the Word"). And then with the emergence of an even larger multitude of multitudes (cells are to humans what humans are to humanity), now there is a new type of "sight". So, white comes back, but on a new higher level of sociocultural abstraction. Not saying that this is necessarily what Garfield had in mind (there's many ways of analyzing structured faction-based lore) Also worth noting that in anthropology, it is proposed that white and black were the first consciously recognized colors, and after that came red, yellow/green, and (most recently) blue. And each cultural shift could roughly be said to be strain between the "old colors" and the "new colors". For example, seeing red added a new dimension to sight other than "on-off" signal, and created a more complex hierarchy of meaning, esp. of blood and nutrition and value.
