Anchored Bixbite

#a71e09
Notes

Anchored Bixbite (#A71E09) is a true red 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 (8°, 90%, 35%) places it in the highly saturated band at a mid 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Anchored
adjective

The past participle of anchor, used since the late nineteenth century as a metaphor for secured in place. As a color word, anchored implies a deep saturated tone that grounds a palette — the dark blues, deep greens, and browns that hold a composition together. Sits in the bold-and-deep corner of the grid alongside solid.

Bixbite
noun

An extremely rare red variety of beryl — found principally in the Wah Wah Mountains of Utah and the Thomas Range. Often called red emerald in the trade. The color refers to a faceted bixbite: a saturated, slightly cool deep red with the gem's signature internal life. Cooler than ruby, deeper than spinel.
