Hands down, B.M. Acadia White.

What ceiling and trim color is best with Bleeker Beige?

Depends on whether the whites throughout the rest of your house are white-white or off-white. Do you have painted or stained cabinets? What color are you windows, white, beige, stained? Is the Bleeker room open and connecting to other rooms or separate?

The existing elements needs to inform the color for the trim.

As far as the ceiling, using Bleeker on the ceiling too is always an option.

SIMPLY WHITE OC117 IS VERY NICE AS WELL
