My next project on the house: Painting the staircase?

Ever since we moved in to our house I’ve wanted to paint our staircase. Mostly because the whole pine look just isn’t for me. Besides after we laid the wood flooring in Merbau, it just didn’t look right.
As the renovation of rooms left are coming to an end, the staircase is approaching fast. I knew I wanted to paint the staircase white, but not sure about the whole case in white or just parts of it. Not to mention which shade of white. There’s like over 100 shades of white!!!
I started going online and looking at pictures of others who have painted the staircase and what shade people recommended.

This is how the staircase looks today…”furuhelvete” as we call it in Norwegian

Some ideas on the style I’m considering:

Our staircase is not a closed one…but you get the idea.

(We are also considering closing the staircase while repainting. But are we taking on more than we can handle???)

Or completely white???

I’m leaning towards this combination…white banister and stained steps

Any comments would be greatly appreciated.
