This is fine. Just remember if any or all of these doors swing into the rooms, when in the open position, the black door will be present. You will only get to enjoy the white door while in the closed position.

Hi Erica, Cashmere, Rockin', in this case, which color to use for the "spine" -- the in-between section of the door ?
Erica, another idea would be to paint or stain a third color (neither black nor white) which would complement both the hallway and the interiors of the bedrooms/bathrooms.
