Bastioned Tanager

#910603
Notes

Bastioned Tanager (#910603) is a deep 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 (1°, 96%, 29%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Bastioned
adjective

Italian bastionato, fortified-with-bastions — past-participle of bastion, derived from bastia (fortified-tower). As a color modifier, bastioned implies a saturated-and-fortified-and-projecting quality, the deep-rich color of Vauban-period military-fortress star-fort projecting-bastion stone-architecture. Sits at the bold-and-fortified end of the grid, parallel to fortified and buttressed.

Tanager
noun

The genus Piranga — particularly P. olivacea, the scarlet tanager of North American summer forests, whose breeding-season males are vivid red with black wings. The color refers to a male scarlet tanager at full breeding plumage: a saturated, slightly cool bright red with the matte finish of carotenoid-pigmented feathers. Brighter than cardinal, warmer than crimson.
