Squared Gown Teal

#15ba9f
Notes

Squared Gown Teal (#15BA9F) is a true teal with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (170°, 80%, 41%) places it in the highly saturated band at a mid 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

Squared
adjective

Latin quadrātus, four-sided — past-participle of square. As a color modifier, squared implies a clear-and-rectilinear-and-orthogonal quality where the hue carries the visual register of right-angle architectural-and-grid alignment. Sits at the crisp-and-balanced end of the grid, parallel to aligned and plumb in usage.

Gown
modifier

Old French goune, long-loose-garment. As a color modifier, gown implies a Tudor-and-Elizabethan-and-formal-evening-gown quality, the visual register of Tudor-and-Elizabethan-and-Worth-couture-gown hand-Tudor-and-Elizabethan-and-formal-evening-gown Tudor-and-Elizabethan-and-Worth-couture-gown-and-Belle-Époque gown-and-Tudor-and-Elizabethan surfaces under Tudor-and-Elizabethan-and-Worth-couture-gown-and-Belle-Époque Hampton-Court-and-Maison-Worth-Paris court-and-couture-light. Sits at the modifier-and-textile end of the grid, parallel to robe and frock 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.
