Can you give us more info?? Ex: what color is your hardware / your fixtures?

I would go with nickle. Or chrome. Make sure your painters do not paint over them.

Satin Nickel Door Hinge 3.5" With 5/8" Radius · More Info

I don’t have any idea about the hardware yet. That’s why I can’t decide between brass or nickel/chrome. White doors and walls are SW Sea Salt. Medium hardwood floors.

Oh gosh the nickel will be beautiful with sea salt since it has a touch of grey depending on lighting.

You need to select your interior doors. The door manufacturer will provide you with your options because your doors will come prehung & usually with nickel hinges as standard.

Unlacquered brass, antique brass, or iron would be the appropriate material choice for a craftsman. Definitely no brushed finishes.

Maybe think outside the box a bit. You could have the hinges powder coated any color you want. So maybe switch things

I would match it to your door hardware. Mixing metals in a space is ok, but I would keep everything on the door the same finish. If you're going for a Craftsman look, I wouldn't use brushed nickel - either oil rubbed bronze or antique/unlacquered brass. Oil rubbed bronze isn't black, but it is dark. Some pieces have areas with warm tones showing through.
