Sturdy Rosaniline

#90156a
Notes

Sturdy Rosaniline (#90156A) 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 (319°, 75%, 32%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

Sturdy
adjective

Old French estourdi, stunned, reckless — drifted in English to mean robust, well-built. Used as a color modifier since the seventeenth century for hues that read as durable and unfussy — the working browns of saddle leather, the working greens of pasture wool. Sits in the bold-and-warm corner alongside robust and solid.

Rosaniline
noun

Synthetic-organic dye class derived from fuchsine, the triphenylmethane free-base of fuchsine hydrochloride synthesized by Verguin and refined by August Wilhelm Hofmann in the early 1860s. Rosaniline color refers to a freshly rosaniline-dyed Mid-Victorian silk taffeta: a saturated, slightly cool deep magenta with the silky luster of synthetic aniline dye. The dye is the basis for crystal violet and gentian violet.
