Salubrious Paraiba

#4eb3de
Notes

Salubrious Paraiba (#4EB3DE) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (198°, 69%, 59%) 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 orange. 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.

Paraiba
noun

The intensely-blue copper-bearing variety of tourmaline — discovered in 1989 in the Brazilian state of Paraíba. Paraiba tourmaline is one of the most expensive gem materials by weight. The color refers to a faceted Paraiba tourmaline: a saturated, slightly cool electric blue-green with the gem's signature internal fire.

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.
