Utilitarian Wire Teal

#177f7c
Notes

Utilitarian Wire Teal (#177F7C) 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 (178°, 69%, 29%) 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

Utilitarian
adjective

Latin ūtilitās, usefulness — adjectival suffix -ian. As a color modifier, utilitarian implies a clear-and-purpose-fit-and-stripped-down quality, the crisp color of Shaker-and-Quaker anti-ornamental functional-and-no-frills craft tradition. Sits at the crisp-and-functional end of the grid, parallel to functional and workmanlike in usage.

Wire
modifier

Old English wīr, wire. As a color modifier, wire implies a thin-drawn-metal quality, the visual register of hand-drawn-and-coiled-wire hand-drawn-and-coiled iron-and-copper-and-gold thin-drawn-metal-wire-and-mesh surfaces under hand-drawn-and-coiled-wire workshop-light. Sits at the modifier-and-texture end of the grid, parallel to mesh and foil 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.
