Bastioned Clematis

#833ca0
Notes

Bastioned Clematis (#833CA0) 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 (283°, 45%, 43%) 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.

Clematis
noun

Asian clematis (Clematis × jackmanii) — a deciduous twining-tendril vine cultivated worldwide as a garden plant, with deep-violet large four-tepalled flowers held above pinnately compound foliage. Clematis color refers to a fully bloomed Clematis × jackmanii tepalled-flower in a Cotswold cottage garden: a saturated, slightly cool deep violet with the velvet finish of fresh broad-tepalled flat-corolla. The genus name comes from the Greek klēmatís (climbing plant).
