Confident Plectranthus

#1e58af
Notes

Confident Plectranthus (#1E58AF) is a true azure with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (216°, 71%, 40%) 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 amber. 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.

Plectranthus
noun

The genus Plectranthus — particularly P. ecklonii, the South African blue spur flower whose fall-blooming blue flower spikes attract sunbirds. The color refers to a fresh P. ecklonii at peak autumn bloom: a saturated, slightly cool deep blue-violet with the matte finish of small clustered mint-family flowers.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
