On this page

Deep Sea Dive, SW 7618, is a dark teal from Sherwin-Williams with hex #376167 and RGB 55, 97, 103. It is the darkest of the paints on this batch of pages, so the main question is how much light your room can spare.

The measurements

HSL is hsl(188, 30%, 31%) and OKLCH is oklch(46.4% 0.048 207.4). The chroma of 0.048 and hue near 207 degrees give a clear blue-green that is cool-leaning, not a neutral. LRV is only 10.269. Anything that low takes in roughly nine tenths of the light that reaches it, which can make a small or north-facing room feel enclosed, and can make a big sunny one feel snug and settled.

Colors this deep are also unforgiving of rough prep. Flaws in the drywall tend to show on dark walls, so plan on proper priming and two coats, and expect the finished surface to look lighter in bright sun than it does in shade.

What the brand pairs it with

Sherwin-Williams lists Extra White (SW 7006), Greek Villa (SW 7551) and Skyline Steel (SW 1015). Extra White and Greek Villa have pages here; Skyline Steel does not. Compare the two whites on a sample board, since both sit very far from this dark wall in lightness.

Worked example

Consider a dining room with one west window and a ceiling you plan to leave white. Painting the lower half of the walls in Deep Sea Dive, with Extra White above the rail and on the trim, gives a crisp line and a cozy lower band. Then picture the same color on a poster or a login page: white text reaches 6.84:1, which passes the 4.5:1 mark for body copy, while black text gets only 3.06:1 and falls short. White is the right choice here.

A practical tip for dark teal walls: choose furniture and art with light edges, since pale shapes stand out sharply against an LRV of 10.269, and add lamps at several heights so the room does not feel like a box.

Same-brand neighbors are far away. Pewter Green (SW 6208) is ΔE 14.6, Peppercorn (SW 7674) is 14.9 and Forestwood (SW 7730) is 15. Those are clearly different colors.

Benjamin Moore offers closer options. Stained Glass (CSP-685) is 3.7, related but visible. Vermont Slate (1673) is 6.8 and Dark Harbor (CSP-720) is 8.4, both clearly different, and Midnight Blue (1638) is 13.2.

Dark colors hide differences on a chip and reveal them on a full wall. If Stained Glass tempts you as a substitute, get a sample of both and see which one holds up in your lamp light.
