Symmetrical Monk Teal

#1b868b
Notes

Symmetrical Monk Teal (#1B868B) 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°, 67%, 33%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

Symmetrical
adjective

Greek symmetría, due-proportion — adjectival suffix -al, derived from sym-metron (with-measure). As a color modifier, symmetrical implies a clear-and-balanced-and-mirrored quality where the hue carries the visual register of bilateral-or-radial proportional symmetry. Sits at the crisp-and-balanced end of the grid, parallel to balanced and aligned in usage.

Monk
modifier

Latin monachus, solitary-religious-man. As a color modifier, monk implies a Cistercian-and-Benedictine-monastic quality, the visual register of Cistercian-and-Benedictine-Monk hand-spun robe-and-cowl-and-scapular Cistercian-and-Benedictine-and-Trappist-monastic surfaces under Cistercian-and-Benedictine-Trappist-monastic hand-spun-robe candlelit-cloister light. Sits at the modifier-and-cultural end of the grid, parallel to friar and nun 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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
