Knightly Hortensia

#a7109b
Notes

Knightly Hortensia (#A7109B) is a true 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°, 83%, 36%) places it in the highly saturated band at a mid 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

Knightly
adjective

Old English cniht, young man / knight — adjectival suffix -ly. As a color modifier, knightly implies a saturated-and-chivalrous-and-medieval quality, the deep-rich color of medieval-English-and-French knight-and-squire armorial-bearings-and-livery tradition. Sits at the bold-and-chivalrous end of the grid, parallel to gallant and cavalier.

Hortensia
noun

French and Italian for hydrangea (Hydrangea macrophylla) — particularly the deep-violet macrophylla cultivars whose color depends on aluminum availability and soil pH. Hortensia color refers to a fully bloomed Hydrangea macrophylla mophead in acidic Breton soil: a saturated, slightly cool deep violet with the velvet finish of dense aluminum-anthocyanin-bonded sepal-flowers. Named after Hortense de Beauharnais, stepdaughter of Napoleon and Queen of Holland.

Display P3 representation

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.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
