Unwavering Disocactus

#ac1b90
Notes

Unwavering Disocactus (#AC1B90) is a true magenta with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (312°, 73%, 39%) 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

Unwavering
adjective

Old English un- (negation) plus wafrian (to flicker). As a color modifier, unwavering implies a saturated-and-constant quality where the hue maintains its full strength without flicker or shift. Sits at the bold-and-firm end of the grid, parallel to steadfast and firm in usage.

Disocactus
noun

Central American orchid cactus (Disocactus ackermannii) — a Cactaceae epiphytic cactus native to Mexican-and-Guatemalan cloud-forests, with deep-magenta funnel-shaped flowers held above flat strap-like stems. Disocactus color refers to a fully opened Disocactus ackermannii funnel-flower in a Veracruz cloud-forest understory: a saturated, slightly cool deep magenta with the velvet finish of fresh fused-petaled funnel-corolla.

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.
