Calm Eden Teal

#12848a
Notes

Calm Eden Teal (#12848A) is a deep cyan 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 (183°, 77%, 31%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Calm
adjective

Latin calma, heat of the day — paradoxically drifted in Italian to mean stillness. Used as a color modifier since the seventeenth century for hues that read as untroubled. Calm blue, calm gray: moderate saturation combined with optical quiet. Sits at the crisp-bucket near quiet and steady.

Eden
modifier

Hebrew ‘Ēden, garden-of-paradise. As a color modifier, eden implies a primal-paradise-and-garden-of-creation quality, the visual register of Genesis-Eden-and-Lucas-Cranach-paradise hand-primal-paradise-and-garden-of-creation Genesis-Eden-and-Lucas-Cranach-paradise-and-Northern-Renaissance eden-and-primal-paradise-and-garden-of-creation surfaces under Genesis-Eden-and-Lucas-Cranach-paradise-and-Northern-Renaissance Cranach-and-Bosch-and-Hieronymus primal-garden-light. Sits at the modifier-and-myth end of the grid, parallel to avalon and bliss in usage.

Teal
noun

Anas crecca, the small dabbling duck whose male in breeding plumage sports a chestnut head crossed by a glossy green-blue stripe. The color refers to that stripe — the iridescent panel just behind the eye: a saturated, slightly muted blue-green with the optical depth of structural color rather than pigment. Cooler than cypress, warmer than cerulean, with the ornithological specificity of a color named for one feather of one bird.
