Hefty Trafalgar

#4d77e4
Notes

Hefty Trafalgar (#4D77E4) 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 (223°, 74%, 60%) 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

Hefty
adjective

Old English hefig, heavy — adjectival suffix -y. As a color modifier, hefty implies a saturated-and-substantial-and-weighty quality where the hue carries the visual heft of a hand-cast pig-iron object. Sits at the bold-and-weighty end of the grid, parallel to substantial and weighty in usage.

Trafalgar
noun

The Cape Trafalgar headland off southern Spain — site of the 1805 Battle of Trafalgar (Nelson's decisive naval victory over Napoleon's fleet). Trafalgar color refers to the deep blue of HMS Victory's preserved hull paint at Portsmouth: a saturated, slightly cool deep blue with the matte finish of period-correct marine paint.

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.
