Aboriginal Sheol

#100017
Notes

Aboriginal Sheol (#100017) is a deep 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 (282°, 100%, 5%) 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 green. 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.

Sheol
noun

Hebrew שְׁאוֹל, the grave / the underworld — the realm of the dead in Tanakh cosmology, sometimes glossed as a deep-pit netherworld and sometimes as a shadowed half-existence. Sheol color refers to a 12th-century Mahzor manuscript's deep-shadow Sheol illumination panel: a saturated, slightly cool deep black with the matte finish of iron-gall ink and lampblack pigment on hand-prepared parchment.
