Confident Erodium

#813cb4
Notes

Confident Erodium (#813CB4) is a true indigo 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 (275°, 50%, 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Confident
adjective

A late-Latin participle, confidens, trusting — borrowed into English in the sixteenth century. As a color modifier, confident implies saturation combined with poise: a confident red doesn't try too hard, just sits at the level of its hue without overreaching. Sits in the bold-bucket center near bold and resolute.

Erodium
noun

Eurasian storksbill (Erodium cicutarium) — a Geraniaceae annual with deep-violet five-petaled cup-flowers and the long-pointed seed-pod shaped like a stork's bill. Erodium color refers to a fully bloomed Erodium cicutarium cup-flower: a saturated, slightly cool deep violet with the velvet finish of fresh small five-petaled cup-corollas. The genus name comes from the Greek erōdios (heron), after the seed-pod shape.
