Bastioned Erodium

#a537ad
Notes

Bastioned Erodium (#A537AD) is a true violet with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (296°, 52%, 45%) 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 green. 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.

Erodium
noun

Eurasian storksbill (Erodium cicutarium) — a Geraniaceae annual with deep-violet five-petaled cup-flowers and the long-pointed seed-pod shaped like a stork's bill. Erodium color refers to a fully bloomed Erodium cicutarium cup-flower: a saturated, slightly cool deep violet with the velvet finish of fresh small five-petaled cup-corollas. The genus name comes from the Greek erōdios (heron), after the seed-pod shape.
