A bit of black.
I love black as an accent color (ugh, I hate the term “accent color”! It’s almost as bad as “feature wall”) in a predominantly white room. I’ve used black paint (Benjamin Moore Toucan Black, a rich, inky-purply black) in various places throughout my house in small amounts—on the stair treads…the fireplace inserts…
…and the pocket doors.
I’ve been thinking about doing a whole wall (moldings and trim included!), though, after seeing these pictures:

The key to making this look good, I think, is in painting the moldings the same color. I don’t love black (or very dark) walls with white trim—the effect is a bit “cartoonish” for me, especially in an older house with more ornate wood/plaster work. The high contrast can make the moldings seem a little overly precious, but a monochromatic floor-to-ceiling (or at least to the picture rail!) paint job looks more modern.
