Indigenous Macadam
Indigenous Macadam (#130739) is a deep indigo 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 (254°, 78%, 13%) 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
Latin indigena, native-born — adjectival suffix -ous. As a color modifier, indigenous implies a neutral-and-native-and-traditional quality, the neutral color of Indigenous-and-First-Nations hand-built-and-tradition-rooted ceremonial-craft pottery-and-textile-and-totem surface-finish. Sits at the neutral-and-traditional end of the grid, parallel to native and aboriginal in usage.
Scottish John Loudon McAdam's 1820s road-paving system — the deep-cool-gray broken-stone compacted road-bed surface of late-Industrial-Revolution Scottish-and-English turnpikes. Macadam color refers to a Glasgow-area macadam-surfaced country-road in November-overcast light: a dark cool-gray with the matte finish of McAdam-system compacted broken-granite-and-bitumen road-bed.

Accessibility
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.
Wide gamut
The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.
Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
