Knightly Violetta

#6445d5
Notes

Knightly Violetta (#6445D5) is a true indigo with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (253°, 63%, 55%) 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 yellow. 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.

Violetta
noun

Italian for little violet (Viola odorata) — the diminutive form of viola, also the name of Verdi's tragic heroine in La Traviata (1853). Violetta color refers to a freshly cut Viola odorata nosegay: a saturated, slightly cool deep blue-violet with the velvet finish of fresh viola petals. Richer than viola (the broader genus name) and less wisteria-warm than glicine.

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.
