Plunged Moonlight

#422787
Notes

Plunged Moonlight (#422787) is a deep indigo with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (257°, 55%, 34%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Plunged
adjective

Old French plonger, to plunge via Latin plumbicāre (to weight with lead) — past-participle of plunge. As a color modifier, plunged implies the deep-and-suddenly-deepened quality of a hue forced into darkness. Sits at the deep-and-rapid-shift end of the grid, parallel to submerged with kinetic register.

Moonlight
noun

The spectrally cool reflected sunlight of a full moon — about 400,000 times dimmer than the sun and slightly redder than direct sunlight due to lunar regolith reflectance, but perceived by dark-adapted scotopic vision as deep blue-violet. Moonlight color refers to a clear-sky landscape under full moonlight as photographed long-exposure: a saturated, slightly cool deep blue-violet with the optical complexity of Purkinje-shifted scotopic-perception lighting.
