Truthful Orion Lagoon

#2cb4d3
Notes

Truthful Orion Lagoon (#2CB4D3) 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°, 65%, 50%) 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

Truthful
adjective

Old English trēowth, truth — adjectival suffix -ful. As a color modifier, truthful implies a clear-and-honest-and-direct quality where the hue carries the visual register of accurate-and-faithful-representation declaration. Sits at the crisp-and-honest end of the grid, parallel to candid and honest in usage.

Orion
modifier

Greek Ὠρίων, hunter-of-the-myth. As a color modifier, orion implies a winter-hunter-and-belt-and-shoulder quality, the visual register of winter-Orion-and-Belt-of-Orion hand-winter-hunter-and-belt-and-shoulder winter-Orion-and-Belt-of-Orion-and-Bortle-1-sky orion-and-winter-hunter-and-belt-and-shoulder surfaces under winter-Orion-and-Belt-of-Orion-and-Bortle-1-sky January-and-February-winter-zenith winter-constellation-light. Sits at the modifier-and-cosmic end of the grid, parallel to rigel and cygnus 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.
