Topsail SW 6217

Topsail LRV and undertone

Sherwin-Williams Topsail (SW 6217) has an LRV of 75, placing it firmly in the light range. Light Reflectance Value indicates how much visible light a color reflects, with 0 representing black and 100 representing white. At 75, Topsail reflects substantial light and has less visual depth than a mid-tone paint. Its listed color family is white, while its calculated undertone is subtly cool blue. That distinction matters when comparing it with neutral whites, which may appear more balanced beside blue-leaning colors. In a room, a light paint can help maintain brightness, although window size, exposure, and artificial lighting also affect the result. North-facing light often reinforces cool undertones, whereas south-facing light tends to introduce warmer illumination. Before painting an entire room, check a sample in morning and evening light. Also compare it with the intended trim, since small undertone differences can become clearer across adjacent white surfaces.

Topsail in other brands

Behr Etched Glass (MQ3-27) is the nearest listed cross-brand match, with an LRV of 75.0 and ΔE of 1.9. The color difference is very small, though it may still be detectable under direct comparison. Benjamin Moore Paper White (OC-55), at LRV 74.41 and ΔE 3.0, is a close but visibly different option. PPG Aria (PPG1001-2) has an LRV of 77 and ΔE of 3.3, placing it in the same close-match category. Benjamin Moore Decorator’s White (OC-149), at ΔE 3.8, also qualifies as close but distinguishable. ΔE expresses the measured difference between colors: below 1 means near-identical, 1 to 2 means very close, 2 to 4 means close but visibly different side by side, and above 4 means only similar. These measurements help narrow alternatives, but they do not guarantee identical results on different surfaces.

Lighter and darker Sherwin-Williams alternatives

Sherwin-Williams Nebulous White (SW 7063) has an LRV of 74, one point below Topsail. It is marginally darker by reflectance. Sherwin-Williams Ice Cube (SW 6252) and Sherwin-Williams Spare White (SW 6203) both have LRVs of 77, making them slightly lighter alternatives. Sherwin-Williams Extra White (SW 7006), at LRV 86, reflects substantially more light and offers a clearer shift toward a brighter finish. These alternatives differ in measured color distance as well as LRV, so equal lightness does not mean equal appearance. For a small room, a higher-LRV option may help the walls reflect more available light. Where a subtle contrast with white trim matters, compare each sample directly against the trim material. Check the colors after they dry and under the room’s actual lighting before selecting one.
