Begin with the weaker light
White Down can be assessed for a north-facing room, but the direction alone cannot determine the result. 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
Begin where White Down meets the permanent white fixture on the least illuminated wall. A pale paint still requires light, and a high LRV cannot make that fixture relationship disappear. Check the daytime boundary and repeat under the lamps that carry the room after sunset.
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 situations that call for another color covers that related choice.
Window size, obstruction and season still matter when choosing White Down. A compass direction is not a brightness measurement. In the Northern Hemisphere, north-facing daylight is often less directly sunlit; the actual room remains the test. The daylight and evening-light checks covers that related choice. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
