Heroic Bengal

#4753bc
Notes

Heroic Bengal (#4753BC) 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 (234°, 47%, 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

Heroic
adjective

Latin hēroicus, of a hero — derived from Greek hērōs. As a color modifier, heroic implies a saturated-and-monumental-and-victorious quality, the deep-rich color of Wagner-and-Sibelius late-Romantic-era musical-and-painterly heroic-mode. Sits at the bold-and-celebratory end of the grid, parallel to triumphant and valiant.

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.
