Befittingly Tar

#040012
Notes

Befittingly Tar (#040012) 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 (253°, 100%, 4%) 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Befittingly
adjective

Old English be- plus fit — adverbial-and-adjectival suffix -ly. As a color modifier, befittingly implies a neutral-and-suitable-and-context-fitting quality where the hue carries the visual register of well-suited-and-appropriately-fitting coordinated color-decision. Sits at the neutral-and-traditional end of the grid, parallel to appropriately and suitably in usage.

Tar
noun

The viscous black liquid produced by distilling pine wood, coal, or peat — used since antiquity for waterproofing ship hulls, weatherproofing roofs, and treating skin conditions. The color refers to fresh pine tar: a deep, slightly muted black with the glossy finish of a viscous oil. Warmer than pitch, deeper than soot, with the maritime weight of a substance whose smell defined every harbor before petroleum.
