Confident Charoite

#573bc0
Notes

Confident Charoite (#573BC0) 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 (253°, 53%, 49%) 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

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.

Charoite
noun

Russian violet-banded mineral mined exclusively along the Chara River in Yakutia, eastern Siberia, since the 1940s. Charoite color refers to a polished Yakutian charoite cabochon: a saturated, slightly cool deep blue-violet with the silky chatoyant finish of fibrous strontium-potassium-calcium silicate. The only deep-violet mineral mined commercially in Russia, valued for its complex banded patterning.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
