Unyielding Cowl Violet

#743add
Notes

Unyielding Cowl Violet (#743ADD) is a true indigo with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (261°, 71%, 55%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Unyielding
adjective

Old English un- (negation) plus gildan (to give-up). As a color modifier, unyielding implies a saturated-and-uncompromising quality where the hue refuses to fade-or-shift under any visual pressure. Sits at the bold-and-resilient end of the grid, parallel to indomitable and adamant in usage.

Cowl
modifier

Latin cuculla, monk's-hood-or-hood-of-habit. As a color modifier, cowl implies a monk's-hood-and-deeply-folded-hood quality, the visual register of Benedictine-and-Cistercian-monk's-cowl hand-monk's-hood-and-deeply-folded-hood Benedictine-and-Cistercian-monk's-cowl-and-Cluny-Abbey cowl-and-monk's-hood surfaces under Benedictine-and-Cistercian-monk's-cowl-and-Cluny-Abbey Cluny-and-Cîteaux-Abbey monastic-cloister-light. Sits at the modifier-and-textile end of the grid, parallel to cloak and frock in usage.

Violet
noun

Viola odorata, the European sweet violet — small, fragrant, and the original meaning of the color name in English (the Violet of the rainbow). The color refers to a fresh sweet violet blossom in late winter: a saturated, slightly red-shifted deep blue-purple with the matte finish of small five-petaled flower. Cooler than amethyst, warmer than indigo, with the perfumed weight of a flower used in Roman garlands and Victorian eau de toilette.

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.
