Steady Mira Lagoon

#0cb3cf
Notes

Steady Mira Lagoon (#0CB3CF) 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 (189°, 89%, 43%) 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

Steady
adjective

Old English stede, place, position — drifted to mean firm and unmoving. Used as a color modifier since the seventeenth century for hues that read as reliable rather than dramatic. Steady gray, steady green: moderate saturation combined with optical calmness. Sits in the crisp-bucket center alongside settled.

Mira
modifier

Latin mira, wonderful-or-marvelous. As a color modifier, mira implies a variable-pulsing-and-red-giant-and-wondrous quality, the visual register of Cetus-Whale-and-variable-Mira-the-Wonder hand-variable-pulsing-and-red-giant-and-wondrous Cetus-Whale-and-variable-Mira-and-Hevelius-discovery mira-and-variable-pulsing-and-red-giant-and-wondrous surfaces under Cetus-Whale-and-variable-Mira-and-Hevelius-discovery 332-day-cycle-and-deep-red-pulse pulsing-stellar-light. Sits at the modifier-and-cosmic end of the grid, parallel to nova and pulsar 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.
