Authoritative Fittonia

#b444a0
Notes

Authoritative Fittonia (#B444A0) is a true magenta with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (311°, 45%, 49%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Authoritative
adjective

Latin auctōritāt-, authority — adjectival suffix -ive. As a color modifier, authoritative implies a saturated-and-formal-imperative quality where the hue carries decisional weight and institutional credibility. Sits at the bold-and-authoritative end of the grid, parallel to commanding and magisterial in usage.

Fittonia
noun

South American nerve plant (Fittonia albivenis) — an Acanthaceae understory creeper native to the Peruvian Amazon whose deep-magenta-veined silver-green foliage is cultivated worldwide as a terrarium plant. Fittonia color refers to a Fittonia albivenis leaf upper-surface in raking light: a saturated, slightly cool deep magenta with the velvet finish of anthocyanin-pigmented vein network against a pale silver-green leaf-tissue background.

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.
