Local Midnight

#100532
Notes

Local Midnight (#100532) 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 (255°, 82%, 11%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Local
adjective

Latin locālis, of-a-place — adjectival suffix -al. As a color modifier, local implies a neutral-and-place-rooted-and-traditional quality, the neutral color of farm-to-table-and-100-mile-diet local-and-place-rooted artisanal-craft food-and-textile-and-pottery surface-finish. Sits at the neutral-and-traditional end of the grid, parallel to regional and vernacular in usage.

Midnight
noun

The color of the sky at midnight on a clear, moonless night, far from city lights — almost black, but with a slight blue cast where star-scattered light reaches the eye. The color refers to that exact moment: a very deep, slightly violet-shifted near-black blue with the optical depth of a sky stripped of every direct light source. Deeper than navy, warmer than ink, with the temporal weight of a name that is a precise hour as well as a color.

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.
