Welcoming Ruff Lagoon

#28afc9
Notes

Welcoming Ruff Lagoon (#28AFC9) 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 (190°, 67%, 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

Welcoming
adjective

Old English wel-cuman, well-coming — present-participle of welcome. As a color modifier, welcoming implies a clear-and-inviting-and-warm quality where the hue carries the visual register of cordial-and-hospitable color-tone. Sits at the crisp-and-cheerful end of the grid, parallel to hospitable and inviting in usage.

Ruff
modifier

Old English ruffe, Elizabethan-pleated-collar. As a color modifier, ruff implies a starched-and-Elizabethan-pleated-collar quality, the visual register of Elizabethan-and-Spanish-Habsburg-ruff hand-starched-and-Elizabethan-pleated-collar Elizabethan-and-Spanish-Habsburg-ruff-and-Holbein-portrait ruff-and-starched-and-Elizabethan-pleated-collar surfaces under Elizabethan-and-Spanish-Habsburg-ruff-and-Holbein-portrait Tudor-and-Spanish-Habsburg-court starched-collar-light. Sits at the modifier-and-textile end of the grid, parallel to gown and frock 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.
