Salubrious Eustoma

#a3b3fb
Notes

Salubrious Eustoma (#A3B3FB) is a soft blue with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (229°, 92%, 81%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Salubrious
adjective

Latin salūbris, healthful — adjectival suffix -ous. As a color modifier, salubrious implies a clear-and-healthful-and-fresh quality, the crisp color of Alpine-and-Sea-air health-resort and Mediterranean-coast spa-and-thalassotherapy outdoor environment. Sits at the crisp-and-wholesome end of the grid, parallel to healthful and bracing in usage.

Eustoma
noun

Mexican-Texan prairie gentian (Eustoma grandiflorum) — marketed worldwide as lisianthus, a long-stemmed cut-flower industry staple with deep-violet rose-form blooms. Eustoma color refers to a freshly cut Eustoma grandiflorum fully opened bloom: a saturated, slightly cool deep blue-violet with the velvet finish of overlapping ruffled tepals. The Greek genus name eu-stoma means fine-mouthed, after the wide-throated corolla.
