What's the one thing

These all have in common?
Olive base cabinets, cream uppers
charcoal and cream
again
rich chocolate and white
and again
gray or stainless, not sure which and white uppers
the island contrast look
and again (LOVE this kitchen - so CLEAN looking!)
island contrast again
oh yeah, another one.

I will paint my kitchen cabinets. And when I do... the uppers will be a different color from the base cabinets. Now if I can just match paint to the hair colors that my border collies shed... (KIDDING!) I will need to purchase the new floor first, no point in needing to repaint if I can't get the color right.
