Weighty Dan

#b51113
Notes

Weighty Dan (#B51113) is a true red with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (359°, 83%, 39%) 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

Weighty
adjective

Old English wegan, to weigh — adjectival suffix -y. As a color modifier, weighty implies a saturated-and-heavy-and-imposing quality where the hue carries visual mass and gravitational presence. Sits at the bold-and-weighty end of the grid, parallel to substantial and hefty in usage.

Dan
noun

The classical Chinese name for vermillion — the cinnabar-and-lead-tetroxide pigment used in Daoist alchemy (dan meaning elixir) and in the painted decoration of Han-period lacquerware. The color refers to dan-pigment on silk: a saturated, slightly orange red with the matte finish of refined mineral. Brighter than zhusha, warmer than vermillion.
