Hefty Enji
Hefty Enji (#B01B05) is a true red with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (8°, 94%, 35%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary cyan. 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.
A dark crimson lake pigment in Japanese textile and lacquer tradition — derived from coccus scale insects and used in the deep underrobes of Heian court dress. The color refers to a enji-dyed silk: a deep, slightly cool dark red with the velvet matte finish of multi-bath dyeing. Deeper than akane, cooler than karakurenai. The hue Murasaki Shikibu would have worn beneath an outer robe.
