Neat Mongol Teal

#1d8586
Notes

Neat Mongol Teal (#1D8586) 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 (181°, 64%, 32%) 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

Neat
adjective

Old French net, clean / pure — sharing root with Latin nitidus. As a color modifier, neat implies a clear-and-orderly quality where the hue carries the well-arranged visual register without clutter or excess. Sits at the crisp-and-orderly end of the grid, parallel to trim and tidy in usage.

Mongol
modifier

Mongolian Mongɣol, Mongol. As a color modifier, mongol implies a steppe-and-Khanate quality, the visual register of Mongol-Khanate-of-Genghis Central-Asian steppe-Empire hand-built ger-and-mounted-cavalry-and-felt-rug-and-Khan-court surfaces under Karakorum-and-Mongolian-steppe Khanate-and-mounted-cavalry open-sky light. Sits at the modifier-and-cultural end of the grid, parallel to tatar and hun 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.
