Tucked Kimono Lagoon

#63f5fa
Notes

Tucked Kimono Lagoon (#63F5FA) is a true cyan with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (182°, 94%, 68%) 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

Tucked
adjective

Old English tūcian, to torment / pull — past-participle of tuck. As a color modifier, tucked implies a clear-and-fitted-and-arranged quality where the hue carries the visual register of carefully-tucked-and-neatly-fitted shirt-into-trouser dress-attire. Sits at the crisp-and-finished end of the grid, parallel to trim and pressed in usage.

Kimono
modifier

Japanese kimono, thing-to-wear. As a color modifier, kimono implies a Japanese-kimono-and-furisode-and-tomesode quality, the visual register of Edo-and-Heian-kimono-and-furisode hand-Japanese-kimono-and-furisode-and-tomesode Edo-and-Heian-kimono-and-furisode-and-Kyoto-Nishijin kimono-and-Japanese-kimono-and-furisode surfaces under Edo-and-Heian-kimono-and-furisode-and-Kyoto-Nishijin Heian-Kyoto-and-Edo-Tokugawa Japanese-court-light. Sits at the modifier-and-textile end of the grid, parallel to haori and sari 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.
