Buttoned Crete
Buttoned Crete (#18B8B8) 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 (180°, 77%, 41%) 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
Old French bouton, button — past-participle of button. As a color modifier, buttoned implies a clear-and-fastened-and-formal quality, the crisp color of Edwardian-period formal-attire fully-fastened-and-formally-dressed gentleman's-attire. Sits at the crisp-and-finished end of the grid, parallel to trim and pressed in usage.
The largest Greek island — and the saturated deep blue of Cretan beach water at Elafonissi and Balos Lagoon. Crete color refers to the lagoon at Balos: a saturated, slightly cool deep blue-green with the optical clarity of warm Aegean water filtered through pink-coral sand.
