Nebulous White SW 7063

Nebulous White LRV and undertone

Sherwin-Williams Nebulous White (SW 7063) has an LRV of 74, which places it in the light range. Light Reflectance Value measures the amount of visible light a paint color reflects, with 0 representing black and 100 representing white. This high value means Nebulous White reflects substantial light and has relatively little visual depth compared with mid-tone colors. Its listed color family is white, and its calculated undertone is neutral. A neutral undertone can make a color easier to compare with other finishes, but surrounding colors and lighting still influence its appearance. For example, a white beside a warmer cream may appear cooler by comparison even when its undertone is neutral. North-facing rooms often receive cooler daylight, while south-facing rooms tend to receive warmer light. Test the paint next to existing trim and flooring, and evaluate the sample at different times before choosing a finish.

Nebulous White in other brands

PPG Aria (PPG1001-2) has an LRV of 77 and ΔE of 1.2, making it a very close cross-brand match. Valspar Modern Gray (8005-1A), with LRV 70 and ΔE 1.5, is also very close despite its lower reflectance. Benjamin Moore Paper White (OC-55) has an LRV of 74.41 and ΔE of 1.8, placing it in the same category. Valspar Seashell Gray (4003-1A), at LRV 69.25 and ΔE 1.8, provides another very close measured match. ΔE describes the measured difference between colors. Values under 1 mean near-identical, 1 to 2 mean very close, 2 to 4 mean close but visibly different side by side, and above 4 mean only similar. These comparisons show why both ΔE and LRV matter: two colors can measure closely while reflecting different amounts of light.

Lighter and darker Sherwin-Williams alternatives

Sherwin-Williams Ice Cube (SW 6252) has an LRV of 77, three points higher than Nebulous White. It is a slightly lighter option by reflectance. Sherwin-Williams Spare White (SW 6203) also has an LRV of 77, giving it the same measured lightness. Sherwin-Williams Topsail (SW 6217), at LRV 75, is one point lighter. Sherwin-Williams Snowbound (SW 7004), with an LRV of 83, reflects more light and is nine points lighter by LRV. These figures help distinguish subtle shifts in brightness, although undertones and surface conditions can still affect the visual result. If you want to coordinate white walls with white trim, compare the samples directly rather than relying on names. Use the same lighting conditions and let the paint dry fully. This approach helps reveal whether small differences become noticeable across large wall and trim surfaces.
