Kindled Rex

#b181f5
Notes

Kindled Rex (#B181F5) is a soft 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 (265°, 85%, 73%) places it in the highly saturated band at a light 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Kindled
adjective

Old Norse kynda, to set on fire — past-participle of kindle. As a color modifier, kindled implies a saturated-and-newly-lit quality, the bright color of autumn-bonfire-and-stove-fire initial-combustion emission. Sits at the bright-and-warm end of the grid, parallel to ignited and aflame in usage.

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.
