Instead of painting your cabinets, you can paint the walls behind the cabinets.
You can also add a back splash on the wall above the counter.
Do you have room for a small island in front of the kitchen? You can purchase one from Pottery Barn or Crate and Barrel.......Look for one in a different color than white.........

You can also change the handles... It will feel "more expensive" if you choose the right ones
(Just take care that the new handles cover the hold holes! ;))

They can but will be prone to chipping. Agree that painting the wall is a better option. Pick a contrasting color from your rug.
