Forthright Kalanchoe

#b31397
Notes

Forthright Kalanchoe (#B31397) 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 (311°, 81%, 39%) 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

Forthright
adjective

Old English forð-riht, straight ahead, direct. Used as a color modifier in Anglo-Saxon-revival contexts for hues that read as honest and unguarded. Forthright red, forthright blue: the saturation is full, the hue is presented without ornamentation or qualification. Sits in the bold-bucket center alongside frank and direct.

Kalanchoe
noun

African Madagascar widow's-thrill (Kalanchoe blossfeldiana) — a Crassulaceae succulent native to Madagascar whose deep-magenta four-petaled flowers in dense terminal corymbs make it a popular winter-bloomer house plant. Kalanchoe color refers to a fully bloomed Kalanchoe blossfeldiana terminal corymb: a saturated, slightly cool deep magenta with the velvet finish of fresh small four-petaled flowers. The genus name comes from the Chinese kalankoe.

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.
