Can you post pics of the space? IMO mixing and matching hardware looks better in a larger space where there is room for your eye to take in all of the variation. In a small space I think it can get chaotic.

Maybe you can purchase and install black hardware for the white cabinets and then see whether you want to add in black or gold.

Please post a picture. Your kitchen sounds like it will be very pretty, but Kendrah is right. One color for hardware is traditional so you don’t add too many colors to the room. It sounds like you have two cabinet colors already.

Even without seeing the kitchen, it sounds chaotic--gold, black, stainless, white, pewter? It's already too much.

Way too many things already and without pics we have no idea what you want from us. IMO too may stars are too many . I think mixing hardware iis never a good choice .
