Sea Salt SW 6204

Sea Salt LRV and undertone

Sherwin-Williams Sea Salt (SW 6204) has an LRV of 63, placing it in the light depth category. Light reflectance value measures how much visible light a color reflects, from 0 for absolute black to 100 for pure white. At 63, Sea Salt reflects a relatively high proportion of light while retaining more color depth than a white. Its color family is green, and its calculated undertone is green. That undertone can look different beside warmer neutrals, cooler grays, or white trim.

Lighting plays an important role in how green paint appears. Cooler north-facing daylight may emphasize differences between green and warm finishes, while south-facing light often brings stronger warmth to a room. Artificial bulbs can also change the perceived balance. Before painting, test a sample near the floor and trim, then review it in morning and afternoon light. This helps you evaluate the color in the conditions where it will actually be seen.

Sea Salt in other brands

Benjamin Moore Quiet Moments (1563) has an LRV of 60.73 and ΔE 1.6, making it a very close measured match. Benjamin Moore Gray Owl (OC-52) has an LRV of 64.51 and ΔE 2.0, also very close by the stated threshold. Behr Light French Gray (720E-2) has an LRV of 61.0 and ΔE 2.5, indicating a close match with a visible difference side by side. Behr Breezeway (MQ3-21), with an LRV of 66.0 and ΔE 3.2, also falls within the close range.

Valspar Tempered Gray (4004-1A) has an LRV of 64.93 and ΔE 3.6, making it another close measured alternative. ΔE below 1 means near-identical, 1 to 2 means very close, and 2 to 4 means close but visibly different side by side. Higher values indicate only similar colors. These measurements cannot account for every lighting or surface condition, so compare samples before choosing a substitute.

Lighter and darker Sherwin-Williams alternatives

Sherwin-Williams Topsail (SW 6217) has an LRV of 75, twelve points above Sea Salt. This higher reflectance may suit a space where a lighter wall surface is preferred. The difference is substantial enough to test against existing trim, particularly if the room contains several pale finishes. A sample helps show whether the additional brightness works with the surrounding colors.

For darker options, Sherwin-Williams Rainwashed (SW 6211) has an LRV of 59, while Sherwin-Williams Comfort Gray (SW 6205) has an LRV of 54. Sherwin-Williams Repose Gray (SW 7015) has an LRV of 58. All three reflect less light than Sea Salt, with Comfort Gray showing the largest reduction. They may suit areas where a deeper wall color is desired. Compare each sample under the room’s actual lighting, because differences in undertone can remain visible even when the LRV relationship is clear.
