Local Crude

#0a0b2b
Notes

Local Crude (#0A0B2B) is a deep blue 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 (238°, 62%, 10%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

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.

Crude
noun

Latin crūdus, raw — adopted into English as the technical term for raw petroleum (crude oil), the deep-iridescent-black multi-component hydrocarbon mixture extracted from Spindletop-style oil-fields. Crude color refers to a freshly extracted West-Texas-Intermediate crude oil sample in a clear-glass cup: a saturated, slightly cool deep black with the iridescent satin finish of multi-component hydrocarbon mixture against the clear-glass background.
