Reinforced Marinaro

#3752dd
Notes

Reinforced Marinaro (#3752DD) is a true blue with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (230°, 71%, 54%) 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

Reinforced
adjective

Latin re- plus inforce — past-participle of reinforce. As a color modifier, reinforced implies a saturated-and-doubled-up-and-strengthened quality where the hue carries layered pigmentation for maximum visual presence. Sits at the bold-and-fortified end of the grid, parallel to fortified and buttressed.

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.
