Can finishes be mixed or should they be uniform? Does the same apply when matching hinges to hardware?
Most people choose to keep their finishes the same for their cabinets, doors, and hinges. Sometimes individuals will incorporate an accent piece (sideboard, cabinet, island) that is painted a different color than the rest of their kitchen and will choose the same style hardware, just in a different finish or a bold accent knob that is a completely different style, like a piece of art. If you choose knobs throughout the whole room, just make sure they are all the same size or a contrasting size for those accent pieces.
