Confident Marinaro

#364dd0
Notes

Confident Marinaro (#364DD0) is a true blue with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (231°, 62%, 51%) 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.

Marinaro
noun

The Italian word for sailor or of the sea — used for the deep blue of marinaro Italian sailor stripes (maglia marinara) and the saturated blue of Italian sailing-club ceremonies. The color refers to an Italian marinaro striped jersey: a saturated, slightly cool deep blue with the matte finish of dyed cotton-and-wool.

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.
