Brass Kitchen

Is there a way around 1980 kitchen cabinet depends on copper appear more money than bronze?
I am refinishing my cabinets kitchen and would like to keep the hinges if possible, but I want to match the silver buttons and pull back will be installing. Then I wondered what you can scratch the coating brass or applying a chemical to move and view its coppery glow of having more money … same if not brilliant. They are like hinges, after all.
The only practical option is to have them chromed. There are usually places in the yellow pages that make that sort of thing.
