Sturdy Larkspur

#4845ac
Notes

Sturdy Larkspur (#4845AC) is a true blue 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 (242°, 43%, 47%) 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 yellow. 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.

Larkspur
noun

Delphinium consolida and its garden cousins — the tall spired wildflower of European meadows whose name means little lark for the spurred shape of its blossoms. The color refers to a fresh larkspur stalk in cottage-garden bloom: a saturated, slightly violet-shifted blue with the matte finish of multi-petaled flowers stacked along a single stem. Cooler than cornflower, warmer than periwinkle, with the literary weight of a flower in Tennyson and Heaney alike.
