Glowy Cardenal

#b66fe5
Notes

Glowy Cardenal (#B66FE5) 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 (276°, 69%, 67%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Glowy
adjective

Old English glōwan, to glow — adjectival suffix -y. As a color modifier, glowy implies a saturated-and-soft-emitting-and-warm quality, the bright color of fireside-and-candle-lit interior atmospheric-warmth surface emission. Sits at the bright-and-warm end of the grid, parallel to glowing and luminous in usage.

Cardenal
noun

Spanish for cardinal — both the ecclesiastical office and the Lobelia cardinalis (cardinal flower) of New World gardens. The Spanish cardenal hat is technically deep red, but the color name slipped into Hispanic-American color terminology for the violet-tinted purples of cassocks. Cardenal color refers to a Spanish capa magna cardinal-cassock: a saturated, slightly cool deep violet with the matte finish of multi-bath ecclesiastical wool.
