mmonika Oh to add to that, what color are your stair treads? If they are painted you could make the handrail the same as your stair threads. And spindles the same as your stair risers...
I honestly don't think you can go wrong with any combination!

Marie Hebson's interiorsBYDESIGN Inc. Hi libaxter, Marie here. Take a look at lots of stairwell pictures, then decide what look you prefer. I'd leave the iron spindles alone. Keep your posts and rail the stained wood colour. Risers, and moulding all white, similar to last photo. Find a picture, and then sand your painted pieces thoroughly. You should get a professional to paint it, as the drips were cause by an amateur painting it. Good Luck!
