Most of my house has oil rubbed bronze fixtures in the bathrooms and kitchen. I want to change all the hardware on my doors to either oil rubbed bronze or brushed nickel. Can I combine these two tones or does the house look better and more consistent with everything the same color? Example would be my bathroom with all oil rubbed bronze sink, towel rack, etc and the the door handle and hinges brushed nickel. Right now handles are dated gold, so everything has to go.
