ummm....Maybe it's because the metal is gray? I don't see why it would be blue, honestly? Have you ever thought the color of the metal is gray and the light is neutral toned? It's not necessarily fluorescent light, honestly if the scene is perfectly white balanced the metal SHOULD be gray. I find blue metal for more strange.

You're right that the colours on the DVD are awful, but unless everything in a space is neutrally coloured, and the lights are all identical, nothing will be perfectly grey. Light bounces around all the over the place (moon landing deniers, I'm talking to you! ;) ) It's often an incredibly subtle effect, but when it's gone your brain knows - there's something about that pic that just makes me squint.

Edit: Radiosity! That's the word I'm looking for:
