See xkcd for how the colors pair. Black becomes gold, and blue becomes white.

I think a big part of the black is being seen as gold because it has a sheen to it and is reflecting yellow light. Blue becoming white might be in response to the interpretation of black as gold.

I originally saw it at home as blue/black, then when I saw it on my work monitor it was initially white/gold. Now, even on my work monitor, it is solidly blue/black.
