Sturdy Helio

#b23aab
Notes

Sturdy Helio (#B23AAB) is a true violet with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (304°, 51%, 46%) 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

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.

Helio
noun

A shortened form of heliotrope — sometimes used as a slightly more genteel color name in late-Victorian fashion catalogues, particularly for the pale lavender-purple silks of mourning dress's transition out of full black. The color refers to a Victorian Helio silk: a soft, slightly muted pale purple with the satiny finish of a fabric dyed to register a specific point in the mourning calendar. Lighter than mauve, cooler than lilac.
