Follow the room through its ordinary day
Judge Cotton under the light you actually use, rather than expecting one constant screen appearance. Its LRV is 83; the key concern is a white specified by code and by its neighbors . Cotton's high LRV supplies a clear lightness reference, but the available description does not support a precise undertone claim.
Why the limestone and white upholstery relationship matters
Limestone and white upholstery create a close palette in which the actual material boundary should decide the preferred white.
Cotton has an LRV of 83; Sherwin-Williams Greek Villa SW-7551 is 84. The difference is 1 points, with Greek Villa returning more light under the reference measurement.
Keep the surroundings in the test
Observe the joint between Cotton and the fixed white at the times the room is used. Keep curtains in their usual positions and avoid judging under a temporary work light. The significant change may be a warmer-looking boundary rather than a dramatic change in overall wall brightness.
A lighting result needs a practical decision
Use the actual stone to assess the white; the published data do not justify a universal undertone promise. The physical-sample checklist covers that related choice.
Record the condition that made Cotton least convincing as well as its best view. If only a short period of daylight works, change the color or the room plan rather than ignoring the hours when the space is occupied. The north-facing room assessment covers that related choice. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
