Snow is white if and only if that's what Eliezer Yudkowsky wants to believe.
Ironically, this is mathematically true. (Assuming Eliezer hasn't forsaken epistemic rationality, that is.) It's just that if Eliezer changes what he wants to believe, the color of snow won't change to reflect it.
If you know more Eliezer Yudkowsky facts, post them in the comments.
