Why didn't you color one of the sides?
It looks like it is coloured, but in a lighter shade of silver so it's not as obvious.
That's pretty spot on. The photos make it harder to tell apart than it is in real life. The silvered parts use a very bright silver that stands out even over the metallic of the puzzle. I tried to make the scheme as close to a metallic version of the traditional cube as possible. Only the metallic orange didn't look that good, so I mixed up some metallic purple and chose that instead. Metallic version of white would be silver, IMHO.
