Hospitable Kimono Lagoon

#3ab1d1
Notes

Hospitable Kimono Lagoon (#3AB1D1) 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 (193°, 62%, 52%) 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

Hospitable
adjective

Latin hospitābilis, of-the-host — adjectival suffix -able. As a color modifier, hospitable implies a clear-and-cordial-and-welcoming quality where the hue carries the visual register of Bed-and-Breakfast and country-inn warm-cordial-host atmosphere. Sits at the crisp-and-cheerful end of the grid, parallel to welcoming and inviting 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.
