Plutonian Salvia

#2f1e8a
Notes

Plutonian Salvia (#2F1E8A) is a deep blue 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 (249°, 64%, 33%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary yellow. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Plutonian
adjective

From Pluto, the Roman god of the underworld (Greek Plouton). As a color modifier, plutonian implies the cool deep darkness of the underworld realms, with literary-classical register. Sits at the deep-and-cool end of the grid, parallel to Hadean and cooler than infernal.

Salvia
noun

The genus Salvia — the sages of the kitchen and ornamental sages of the garden — over 900 species, many with vivid blue-violet flower spikes that distinguish ornamental cultivars from culinary forms. The color refers to a fresh Salvia farinacea (mealy-cup sage) spike: a saturated, slightly violet-shifted blue with the matte finish of small lipped flowers along a single stem. Cooler than veronica, warmer than larkspur.

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.
