Unyielding Kusumbha

#b4007e
Notes

Unyielding Kusumbha (#B4007E) is a true 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 (318°, 100%, 35%) places it in the highly saturated band at a mid 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

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.

Kusumbha
noun

Sanskrit कुसुम्भ, safflower (Carthamus tinctorius) — the floral source of the deep red-pink dye used in Vedic-period Indian textiles and as the kumkuma powder of Hindu and Buddhist ritual. Kusumbha color refers to a freshly pressed Carthamus tinctorius petal-extract on Indian cotton: a saturated, slightly cool deep magenta with the matte finish of safflower-pigment-dyed hand-spun cotton.

Wide gamut

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.
