Smouldered Bluegrass

#073f2a
Notes

Smouldered Bluegrass (#073F2A) is a deep teal with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (158°, 80%, 14%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Smouldered
adjective

From Old English smolderian, to burn slowly — past-participle of smoulder. As a color modifier, smouldered implies the deep glowing-dark quality of fire-warmed embers, where the underlying hue retains warmth even at low lightness. Sits at the deep-and-warm end of the grid, somewhere between charred and burnt.

Bluegrass
noun

Poa pratensis, Kentucky bluegrass — the cool-season turf grass that dominates lawns of the American Northeast and Midwest. Bluegrass music takes its name from the same plant via Bill Monroe's bluegrass-state Kentucky band. The color refers to a fresh-mown Kentucky bluegrass lawn: a soft, slightly cool blue-green-gray with the matte finish of cropped grass.
