Bastioned Pyrope

#ac1f2f
Notes

Bastioned Pyrope (#AC1F2F) is a true red with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (353°, 69%, 40%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary teal. 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.

Pyrope
noun

A magnesium-aluminum garnet variety — the deeper, more saturated red of fine garnets from Czech, South African, and Tanzanian sources. The color refers to a faceted Bohemian pyrope: a saturated, slightly cool deep red with the gem's signature internal life. Deeper than almandine, warmer than ruby.
