I think that the color white is used by Christians (of which I am one) b/c it is the absence of all color, thus it represents the absence of self, or in the terms of the church "complete surrender to something greater than yourself". Black, though, is the presence of all color and can thus symbolize will and intellect, etc. Plus its a cool color. And yes, black is often interpreted as evil; when I bought my first black shirt my parents asked me if I was becoming a goth (IMG:
