Princely Hesperis
Princely Hesperis (#7B0B72) is a deep violet 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 (305°, 84%, 26%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin prīnceps, first / chief — adjectival suffix -ly. As a color modifier, princely implies a saturated-and-royal-secondary quality, the deep-rich color of European crown-prince coronet-and-livery vestment. Sits at the bold-and-aristocratic end of the grid, parallel to lordly and regal in usage.
Eurasian Dame's rocket (Hesperis matronalis) — an evening-fragrant Brassicaceae perennial whose deep-violet four-petaled flowers naturalized across European hedgerows since the Roman era. Hesperis color refers to a fully bloomed Hesperis matronalis terminal raceme: a saturated, slightly cool deep violet with the velvet finish of fresh four-petaled flowers. The genus name comes from the Greek hespéra (evening), after the dusk-fragrance peak.

Accessibility
How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.
Wide gamut
The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.
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.
