Reposeful Tiānlán

#87f0f4
Notes

Reposeful Tiānlán (#87F0F4) is a soft 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°, 83%, 74%) places it in the highly saturated band at a light 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

Reposeful
adjective

Latin repōnere, to put back — adjectival suffix -ful. As a color modifier, reposeful implies a clear-and-restful-and-still quality, the calm color of pre-modern monastic cloister-and-refectory meditative-and-silent interior architecture. Sits at the crisp-and-calm end of the grid, parallel to peaceful and placid in usage.

Tiānlán
noun

Chinese for sky-blue — combining tiān (sky) and lán (blue). Used for the pale blue of clear-sky painting in Chinese landscape tradition and the tiānlán-cí (sky-blue glaze) of Song-dynasty porcelain. The color refers to a Song tiānlán glaze: a soft, slightly cool pale blue with the high gloss of fired ceramic glaze.
