Give this sample a clear job
Sample Sherwin-Williams Cotton SW-9581 beside the fixed finishes, in the intended orientation and under normal room lighting. The trial should settle 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 comparison fair
Label the Cotton board and hold it directly against each permanent white, with equal lighting and orientation. Include the intended trim finish in the last trial. The approved sample should resolve the actual white-to-white boundaries, rather than simply look pleasant on blank paper.
Approve the actual coating and the least favorable view
Use the actual stone to assess the white; the published data do not justify a universal undertone promise.
Keep the approved dried board with the complete Sherwin-Williams SW-9581 product and finish specification. Follow the actual coating instructions for application, drying and preparation; the color name does not settle those requirements. The daylight and evening-light checks covers that related choice. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
