Symmetrical Vita Lagoon

#1eb2d2
Notes

Symmetrical Vita Lagoon (#1EB2D2) 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 (191°, 75%, 47%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Symmetrical
adjective

Greek symmetría, due-proportion — adjectival suffix -al, derived from sym-metron (with-measure). As a color modifier, symmetrical implies a clear-and-balanced-and-mirrored quality where the hue carries the visual register of bilateral-or-radial proportional symmetry. Sits at the crisp-and-balanced end of the grid, parallel to balanced and aligned in usage.

Vita
modifier

Latin vita, life-or-living. As a color modifier, vita implies a Latin-life-and-living-quality quality, the visual register of Roman-vita-and-dolce-vita-Latin-life hand-Latin-life-and-living-quality Roman-vita-and-dolce-vita-Latin-life-and-Vergilian-pastoral vita-and-Latin-life-and-living-quality surfaces under Roman-vita-and-dolce-vita-Latin-life-and-Vergilian-pastoral Augustan-Rome-and-Renaissance-Italy living-Roman-light. Sits at the modifier-and-Latin end of the grid, parallel to amor and via 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.
