Candid Kona

#18907d
Notes

Candid Kona (#18907D) is a deep teal with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (171°, 71%, 33%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

Candid
adjective

Latin candidus, bright-white / honest — derived from candēre (to shine). As a color modifier, candid implies a clear-and-honest-and-direct quality where the hue carries the visual register of straightforward-honest declaration. Sits at the crisp-and-honest end of the grid, parallel to frank and plainspoken in usage.

Kona
noun

The leeward (western) coast of the Big Island of Hawaii — and the deep blue-green of Kona's Kealakekua Bay and Honaunau coves. Kona color refers to the bay water at midday: a saturated, slightly cool deep blue-green with the optical clarity of cold Pacific water against volcanic black-sand beaches.
