Local Ink

#100829
Notes

Local Ink (#100829) 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°, 67%, 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 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.

Ink
noun

A dark fluid for writing or printing — historically gallic-acid-and-iron-sulfate solutions for European manuscript ink, lampblack-and-glue suspensions for Chinese sumi ink, octopus pigment for the seppia of Mediterranean shellfish ink. The color refers to fresh black ink on white paper: a saturated, slightly cool near-black with the matte finish of dried pigment in a binder. Cooler than coal, deeper than soot.
