Follow the room through its ordinary day
Judge White Down under the light you actually use, rather than expecting one constant screen appearance. Its LRV is 76.69; the key concern is 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 surroundings in the test
Observe the joint between White Down 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.
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. The physical-sample checklist covers that related choice.
Record the condition that made White Down 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.
