Central Petrol

#1f0112
Notes

Central Petrol (#1F0112) is a deep magenta 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 (326°, 94%, 6%) 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Central
adjective

Latin centrālis, central — adjectival suffix -al. As a color modifier, central implies a neutral-and-central-and-balanced quality where the hue carries the visual register of Mid-Century-Modern and Bauhaus central-and-balanced-and-grounded foundational-design fundamental-element. Sits at the neutral-and-foundational end of the grid, parallel to core and grounded in usage.

Petrol
noun

French pétrole, rock oil — the deep-iridescent-black raw-petroleum residue at La Brea and other natural-seep sites, distinct from the refined liquid-fuel sense of British English petrol. Petrol color refers to a freshly extracted La Brea Tar Pit raw-petroleum-puddle in midday sun: a saturated, slightly cool deep black with the iridescent satin finish of multi-component hydrocarbon residue against suspended-clay particulate.
