Ceilings usually do well with a flatter, matte finish. It hides small imperfections and reduces glare from overhead lights. Walls, on the other hand, often benefit from an eggshell or low-sheen finish that’s a bit more washable.
Using separate finishes plays to their strengths: ceilings look smooth and recede quietly overhead, while walls can handle the occasional wipe-down without looking patchy.
You’re still in the same colour family, but the performance is tuned to each surface’s job.
