Painting Vaulted Ceiling Same Color As Walls. Rooms with tall vaulted white ceilings can make the space feel cold and bare. Vaulted ceilings are tricky.
Deeper colors give this ceiling. It looks like a huge diaper or tissue that is stuck on the ceiling. Since ceilings often appear in shadow the resulting lighter shade color relates favorably to the wall color and creates the illusion of higher ceilings.
This will help in making the ceiling appear lower and cozier.
To shrink this space you can paint the ceilings two to three shades darker than the walls. Rooms that are smaller or have lower ceilings benefit from lighter colored ceilings. Never do the same color on walls and ceiling when there is crown molding it just looks lazy like the whole thing was sprayed by the builder and then crown put up. Another option could be to paint the ceiling the same colour as the walls.
