I'm always drawn to painted white wood floors because of how they make everything look bright, airy, and etherial. They make the furnishings of a room seem to float in the most magical way. And, when paired with white walls, they can make any style of space look updated and modern.
Two things to keep in mind with white floors:
1) You must have some amazing art or architectural focal points to showcase, or use splashes of color in accessories to ground the space and keep it from looking like you live in a two-deminsional world.
What do you think of white floors? Are they a "do" or a "don't"?
