Lordly Rex

#7b0daf
Notes

Lordly Rex (#7B0DAF) 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 (281°, 86%, 37%) 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

Lordly
adjective

Old English hlāford-līc, lord-like — adjectival suffix -ly. As a color modifier, lordly implies a saturated-and-aristocratic-and-haughty quality, the deep-rich color of pre-modern English-and-French manorial-aristocracy livery and hereditary-estate household-textile. Sits at the bold-and-aristocratic end of the grid, parallel to princely and patrician.

Rex
noun

Latin rex, king — adopted into English as the technical term for imperial purple-and-gold regalia. The rex color tradition refers to the Tyrian purple imperial robes of Roman emperors after Diocletian's 295 CE vestiarium reforms. Rex color refers to an imperial Roman purpura-dyed paludamentum cloak: a saturated, slightly cool deep violet with the matte finish of multi-bath Tyrian shellfish-dye on Roman imperial wool.

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.
