Reposeful Nasturtium

#903b01
Notes

Reposeful Nasturtium (#903B01) is a deep orange 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 (24°, 99%, 28%) places it in the highly saturated band at a dark 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 azure. 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.

Nasturtium
noun

Tropaeolum majus, the South American climbing plant naturalized as a kitchen-garden flower across Europe. Nasturtium (from the Latin naris-torquere, nose-twisting, for the peppery flavor) has edible leaves and saturated red-orange flowers. The color refers to a fresh T. majus bloom: a saturated, slightly red orange with the satin finish of bee-pollinated flower. Brighter than carrot.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
