I've seen a lot of guys paint up this Khurasan robot (left) in a more colored ceramic style, as opposed to steel and chrome. My effort just wound up looking garish. Lesson learned - paint up the chrome underneath and then pick out the ceramic plates later.
If you ever paint up the short bot on the right (from 15mm.co.uk), I'd suggest using a small disc to elevate the figure off the base. He has a sort of hovercraft blower style balloon base, you can't see it in these photos, that would look great hovering a mm or two off the figure base.
