Robust Mauve

#a345c7
Notes

Robust Mauve (#A345C7) is a true violet 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 (283°, 54%, 53%) 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

Robust
adjective

From the Latin robustus, of oak — implying strength combined with substance. As a color modifier, robust describes saturation combined with body: a robust burgundy, a robust olive. Sits in the bold-and-warm corner alongside strong and solid, with the slightly textural implication of a color that has substance behind the pigment.

Mauve
noun

The first synthetic aniline dye — an accidental product of William Perkin's 1856 attempt to synthesize quinine, which yielded a stable purple instead. Mauve (French for mallow) became the chemical-industry breakthrough that reshaped textile coloring. The color refers to a freshly mauve-dyed silk: a soft, slightly red-shifted pale purple with the slight luster of synthetic-dyed natural fiber. Lighter than violet, warmer than lilac, with the industrial-history weight of the pigment that founded modern chemistry.
