Surveyed Grace Teal

#31a7da
Notes

Surveyed Grace Teal (#31A7DA) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (198°, 70%, 52%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Surveyed
adjective

Old French surveer, to look upon — past-participle of survey. As a color modifier, surveyed implies a clear-and-measured-and-coordinated quality, the crisp color of Mason-Dixon-Line-and-Royal-Navy-Hydrographic scientific-and-cadastral land-and-sea surveying tradition. Sits at the crisp-and-mapped end of the grid, parallel to mapped and plotted in usage.

Grace
modifier

Latin gratia, favor-or-thankfulness. As a color modifier, grace implies a flowing-and-elegant-and-blessed quality, the visual register of Botticelli-Three-Graces-and-Apollonian-grace hand-flowing-and-elegant-and-blessed Botticelli-Three-Graces-and-Apollonian-and-Renaissance-classical graced-and-flowing-and-elegant-and-blessed surfaces under Botticelli-Three-Graces-and-Apollonian-and-Renaissance-classical chiton-and-laurel-wreath-and-fountain Florentine-pavilion-light. Sits at the modifier-and-mood end of the grid, parallel to charm 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.

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.
