What color to paint my kitchen walls to brighten it up?

the cabinets are a medium oak built in the 80s,floor is a dark not ebony wood.The cabinets have a soffit that makes the cabinets look heavy.Counter tops would be a neutral.2 wooden doors in kitchen to deck and to carport.don't want to paint the cabinets.No yellows please.What would you suggest the room has a chair rail with dark paneling below and drywall above.would like a two tone.
