Hefty Lupin
Hefty Lupin (#6F5AE1) 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 (249°, 69%, 62%) 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
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.
The genus Lupinus — North American and European legumes whose tall blue-violet flower spikes appear in alpine meadows and cottage borders. The Latin lupus, wolf, references the old (incorrect) belief that the plant depleted soil. The color refers to a fresh blue lupin spike: a saturated, slightly violet-shifted blue with the matte finish of stacked pea-family flowers. Cooler than larkspur, warmer than wisteria, with the high-meadow weight of a perennial that tolerates poor soil.
