stair rail in maple stained in Jacobean
black handrail with gloss stain
The finish looks super consistent, so my guess is that it's painted and they did a beautiful job. The white could be any white you like--Ben Moore's Super White is a good place to start (these spindles do look super!). And I really think the black is just that--black. It's deep and rich, with a nice gloss finish.
