Three colours, yeah? There are some very high gloss metals and stuff like metalic paint, but even those need a few more shades especially if you have curved surfaces.
And I think hapiel is correct with his last sentence, it is a wiki written from your subjective perspective and lacks objectivity.

I know you want to think I'm some kind of idiot, or overall not as intelligent as you, but it's really not a good idea. For one thing, you know nothing about me. For all you know, I'm one of the most if not the most intelligent individual alive. Whether I am or not, it's really not a good idea to underestimate me, as it tends to result in major humiliation on the part of the underestimator, which results in turn in lost reputation and attitude hardening which tends to trigger descent into delusional disconnect, among other psychological maladies.
By the by, you might want to stick around for a particularly good show I intend to put on at Bugzilla tonight. You'll need to do some catching up to understand what's happening, but it'll be worth the price of admission I assure you.
