Indomitable Magenta

#99017f
Notes

Indomitable Magenta (#99017F) is a deep magenta 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 (310°, 99%, 30%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Indomitable
adjective

Latin indomitābilis, unconquerable — derived from domāre (to tame). As a color modifier, indomitable implies a saturated-and-unconquerable-and-fierce quality where the hue resists any attempt to subdue or modulate its presence. Sits at the bold-and-resilient end of the grid, parallel to unyielding and adamant.

Magenta
noun

A synthetic aniline dye (fuchsine) introduced in 1859 and renamed in 1860 to commemorate the Franco-Sardinian victory over Austria at the Battle of Magenta in northern Italy. The dye produced the first vivid pink-purple textile color cheaply available to mass markets. The color refers to a freshly magenta-dyed silk: a saturated, slightly cool deep pink-purple with the satiny finish of synthetic-dyed natural fiber. Cooler than fuchsia, warmer than violet.

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.
