Hefty Bengal

#6a51aa
Notes

Hefty Bengal (#6A51AA) is a true indigo with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (257°, 35%, 49%) 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 lime. 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.

Bengal
noun

Historical Indian region (modern West Bengal and Bangladesh) — the colonial-era epicenter of Indigofera tinctoria cultivation, where the British East India Company forced peasant cultivators (ryots) into the nij indigo system. Bengal color refers to a Bengali handloom kantha embroidered cotton dyed in neel: a saturated, slightly cool deep blue-violet with the matte finish of fermentation-vat indigo on hand-loomed cotton.

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.
