Stamped Vesta Lagoon

#13c8d5
Notes

Stamped Vesta Lagoon (#13C8D5) 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 (184°, 84%, 45%) 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

Stamped
adjective

Old English stempan, to stamp — past-participle of stamp. As a color modifier, stamped implies a clear-and-impressed-and-repeating quality, the crisp color of William-Morris-and-Liberty-of-London block-printed-textile carefully-impressed pattern. Sits at the crisp-and-printed end of the grid, parallel to printed and engraved in usage.

Vesta
modifier

Latin Vesta, Roman-goddess-of-hearth. As a color modifier, vesta implies an asteroid-and-hearth-flame-and-bright-and-rocky quality, the visual register of Vesta-asteroid-and-Roman-hearth hand-asteroid-and-hearth-flame-and-bright Vesta-asteroid-and-Roman-hearth-and-Dawn-mission vesta-and-asteroid-and-hearth-flame-and-bright surfaces under Vesta-asteroid-and-Roman-hearth-and-Dawn-mission asteroid-belt-and-Vestal-Temple sacred-flame-light. Sits at the modifier-and-cosmic end of the grid, parallel to ceres and juno in usage.

Lagoon
noun

A shallow body of saltwater partially or fully enclosed by a barrier — coral atoll lagoons in the Pacific, Venice's Laguna Veneta, the Florida Keys' backcountry. The color refers to the average reflectance of a calm tropical lagoon at midday: a saturated, slightly muted blue-green with the optical clarity of shallow water over white sand. Brighter than reef, cooler than aquamarine, with the postcard weight of a Pacific atoll seen from above.

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.
