Seriously, I'm all in with the white woodwork. I would not paint the hand rail. You don't want to use paint - esp latex, on any surface that gets a lot of handling. Even if you were willing to clean it fastidiously, paint wouldn't stand up to that either. And good wood grain always looks richer anyway.
The color is close to the color we painted our previous house, maybe a shade or two darker. We used a a two shade light/dark combo and that is a little darker than our darker pick. Now to be honest, we knew we were selling that house so we picked more neutral hues then we might have if we didn't care about that. We would normally go for more color - the current house is mostly in light greens. But of the neutral palettes I prefer beiges to grays - I don't care if that's old school - grays are cold.
