Confident Blueberry
Confident Blueberry (#3690E5) 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 (209°, 77%, 55%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary orange. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
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.
The genus Vaccinium — North American native berry shrubs cultivated since the early twentieth century. The fruit's deep blue-purple skin is colored by anthocyanin and the protective bloom of waxy yeast cells. The color refers to a fresh wild blueberry: a saturated, slightly cool deep blue-violet with the powdery finish of waxy fruit surface.

Accessibility
How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.
Wide gamut
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.
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.
