Fading Cataract

#375f63
Notes

Fading Cataract (#375F63) is a deep cyan 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 (185°, 29%, 30%) places it in the muted 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Fading
adjective

Old French fader, to fade — present-participle of fade. As a color modifier, fading implies a hushed-and-receding-and-thinning quality where the hue carries the visual register of sun-faded-and-light-bleached multi-month-or-decade gradual-fading color-amplitude. Sits at the hushed-and-fading end of the grid, parallel to waning and dimming in usage.

Cataract
noun

A large waterfall with significant volume — particularly the Cataracts of the Nile and the Iguaçu Cataract of South America. Cataract color refers to the deep blue-white of high-volume falling water at Iguaçu: a saturated, slightly cool deep blue-white with the optical brightness of micron-scale air-water mixing.
