Aboriginal Quasar

#040521
Notes

Aboriginal Quasar (#040521) is a deep blue 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 (238°, 78%, 7%) places it in the highly saturated band at a dark 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Aboriginal
adjective

Latin ab origine, from-the-beginning — adjectival suffix -al. As a color modifier, aboriginal implies a neutral-and-original-and-indigenous quality, the neutral color of Aboriginal-Australian dot-and-X-ray-painting traditional-and-original earth-and-mineral-pigment ceremonial-craft tradition. Sits at the neutral-and-traditional end of the grid, parallel to indigenous and native in usage.

Quasar
noun

Astronomical quasi-stellar object — supermassive-black-hole-powered Active Galactic Nucleus whose event horizon gives the deepest-known absolute light-extinction in the observable universe. Quasar color refers to a 3C 273 event-horizon dark-disc as imaged by the Event Horizon Telescope: a saturated, slightly cool deep black with the optical complexity of gravitational-lensing-and-relativistic-jet emission from the surrounding accretion disk.
