Replete Sunstone

#b13918
Notes

Replete Sunstone (#B13918) 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 (13°, 76%, 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

Replete
adjective

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.

Sunstone
noun

A feldspar variety with copper-mineral inclusions that scatter light into a flickering orange-red sheen. Mined principally in Oregon (the only US state with sunstone as official gem) and Norway. The color refers to a polished Oregon sunstone cabochon: a saturated, slightly red orange with the optical complexity of light scattering off internal copper plates. Warmer than citrine.
