Replete Citron
Replete Citron (#828D0B) is a deep yellow 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 (65°, 86%, 30%) places it in the highly saturated band at a dark 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 blue. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin replētus, filled — past-participle of replēre. As a color modifier, replete implies a saturated-and-fully-pigmented quality where the hue is completely loaded with its source pigment. Sits at the bold-and-saturated end of the grid, parallel to brimming and suffused in usage.
Citrus medica, the ancestral citrus from which lemons, limes, and oranges all descend through hybridization. The fruit reached Europe before lemons and gave its name to the pale, slightly green yellow of its thick rind. Cooler than lemon, lighter than chartreuse, with the candied aroma of the Jewish etrog and the medieval European preference for the rind over the flesh. Cédrat in French; cedro in Italian.
