I am building a house & we plan to have a classic white kitchen with marble & polished nickel hardware. Most of our bathroom fixtures are either polished nickel or polished chrome. We will have lights (e.g. sconces) that will be either polished nickel &/or polished chrome & also lighting that has bronzed metal. Is it ok to have door hardware that is oil rubbed bronze? How common is it to split a door's hardware in that the outside knob is oil rubbed bronze & the inside knob is polished nickel/chrome. I heard this was called "splitting"? Any advice would be great...
