Rural Eclipse

#15021a
Notes

Rural Eclipse (#15021A) 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 (288°, 86%, 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

Rural
adjective

Latin rūrālis, of-the-countryside — adjectival suffix -al. As a color modifier, rural implies a neutral-and-country-and-traditional quality, the neutral color of American-and-English-Country rural-and-traditional farmhouse-and-cottage interior-decoration-and-textile surface-finish. Sits at the neutral-and-traditional end of the grid, parallel to country and pastoral 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.
