Bastioned Clematis

#811a92
Notes

Bastioned Clematis (#811A92) is a deep violet 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 (292°, 70%, 34%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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).

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
