Light colours create space, and obviously, light. If you have
a small room, or one that doesn’t receive much natural light, painting it a
lighter color will instantly create a sense of space.
Painting the ceiling of a room darker will lower it, and
shorten a tall, lanky space. This look is strengthened further by extending the
ceiling color down the wall to a picture rail or Scotia. This can be useful in
disproportionately small rooms with tall ceilings, to balance the space. It can
also create a cozy feeling of warmth.
Coupling the dark ceiling, continued onto the wall with a
dark floor will visually lower the ceiling
