Pillowed Seagrass

#678e8a
Notes

Pillowed Seagrass (#678E8A) is a true teal with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (174°, 16%, 48%) places it in the muted band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Pillowed
adjective

Old English pyle, pillow — past-participle of pillow. As a color modifier, pillowed implies a hushed-and-cushioned-and-soft quality where the hue carries the visual register of Anglo-Saxon and Norman down-stuffed-and-pillowed bedding-textile soft-finish. Sits at the hushed-and-soft end of the grid, parallel to cushioned and padded in usage.

Seagrass
noun

Marine flowering plants — distinct from algae — that form underwater meadows in shallow coastal waters worldwide. Genera include Zostera, Posidonia, Thalassia. The color refers to a tropical seagrass meadow at low tide: a soft, slightly cool deep blue-green with the satin finish of submerged grass-leaves.
