Replete Blueschist

#4478dd
Notes

Replete Blueschist (#4478DD) 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 (220°, 69%, 57%) 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 amber. 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.

Blueschist
noun

A metamorphic rock — formed under low-temperature high-pressure conditions in subduction zones — characterized by the deep blue of glaucophane amphibole. The color refers to a freshly cut blueschist specimen: a soft, slightly cool deep blue with the metallic-gray-fibrous finish of crystallized amphibole.
