Replete Niger

#397ed8
Notes

Replete Niger (#397ED8) is a true azure with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (214°, 67%, 54%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary orange. 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.

Niger
noun

The third-longest river in Africa — flowing through Guinea, Mali, Niger, Benin, and Nigeria to the Gulf of Guinea. Niger color refers to mid-depth Niger River water at Timbuktu in Mali: a saturated, slightly cool deep blue-brown with the optical complexity of West African inland-delta river water.
