Vega is "white" only because the standard filters are normalized to give it a B-V of zero. Again, astronomical color is a quantitative value that isn't directly related to physiological color. Astronomically, the color of a star is basically just a measure of its temperature.
Ladies and Gentlemen of the jury,
I am now going to present photographic evidence that white Vegas actually exist!
