Local Eclipse

#100323
Notes

Local Eclipse (#100323) 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 (264°, 84%, 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 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.

Eclipse
noun

The total occlusion of the sun by the moon — the brief event during which the sky goes from full daylight to deep blue-black in the four to seven minutes of totality. The color refers to the sky at the centerline of total eclipse: a deep, slightly violet-shifted near-black with the optical complexity of a sky still receiving the sun's corona. Cooler than midnight, warmer than vantablack, with the celestial weight of a phenomenon visible at any single location once every few centuries.
