I have been thinking about the same thing recently. I have a white Leopold fc200r and want some new caps, I have been after black engraved PBT. I was tempted by white, but the off white colour of the Leo may look strange.
I am just waiting to hear back from feng to see if he has any black engraved with a space bar that fits the silly Leo spacing.
I am just debating what to accent I with, I have some sexy green PBT engraved, but I also have some red keys which would go well, decisions, decisions.
So yeah, my vote goes for black and one other colour, one for the modifiers and the other for the rest, switch around to suit
