Mended Cataract

#668b8b
Notes

Mended Cataract (#668B8B) is a true 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 (180°, 15%, 47%) places it in the muted 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Mended
adjective

Old English mendan, to mend — past-participle of mend. As a color modifier, mended implies a hushed-and-repaired-and-restored quality, the hushed color of multi-decade Japanese-boro heavily-mended-and-stitched indigo-cotton-and-hemp work-clothing. Sits at the hushed-and-worn end of the grid, parallel to patched and darned 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.
