Dense Yaqut

#b5050c
Notes

Dense Yaqut (#B5050C) 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 (358°, 95%, 36%) 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

Dense
adjective

Latin dēnsus, thick / crowded — sharing root with English condense. As a color modifier, dense implies a saturated-and-tightly-packed quality where the hue carries maximum pigmentation per visual unit-of-area. Sits at the bold-and-saturated end of the grid, parallel to thick and concentrated in usage.

Yaqut
noun

The Arabic word for ruby and other precious red gems — used across Islamic poetry from al-Mutanabbi onward as a metaphor for the lips of beloved or the wine in a goblet. The color refers to a polished Yemeni red garnet or Burmese ruby: a saturated, slightly cool deep red with the gem's signature internal life. Cooler than ruby, deeper than crimson.
