Primal Jet
Primal Jet (#190224) 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 (281°, 89%, 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin prīmālis, first — adjectival suffix -al, derived from prīmus (first). As a color modifier, primal implies a neutral-and-original-and-foundational quality where the hue carries the visual register of cave-painting-and-prehistoric-art original-and-foundational-mineral-pigment color-decision. Sits at the neutral-and-foundational end of the grid, parallel to primary and primal in usage.
Fossilized wood from the Araucaria coniferous trees of the Jurassic period — compressed for 180 million years into a hard, polishable lignite. Mined principally at Whitby on the Yorkshire coast since the Bronze Age and worn as Victorian mourning jewelry after Albert's death in 1861. The color refers to a polished Whitby jet cabochon: a deep, slightly muted near-black with the satin finish of fossilized wood.

How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.
