Give this sample a clear job
Sample Benjamin Moore White Down OC-131 beside the fixed finishes, in the intended orientation and under normal room lighting. The trial should settle a cream-white scheme built around the stone first . White Down has more color depth than Ivory White, useful when a very light cream fails to frame warm stone.
Limestone's broad background should guide the white choice; isolated veins and small linen samples can otherwise distract from the permanent surface.
Keep the comparison fair
Label the White Down 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.
White Down has an LRV of 76.69; Benjamin Moore Soft Chamois OC-13 is 77.4. The difference is 0.71 points, with Soft Chamois returning more light under the reference measurement.
The condition for keeping White Down
Use the stone's background color as the reference, then decide whether the trim should be closer or cleaner. The undertones and neighboring colors covers that related choice.
Keep the approved dried board with the complete Benjamin Moore OC-131 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.
