Withheld Freshet

#517d7b
Notes

Withheld Freshet (#517D7B) 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 (177°, 21%, 40%) 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

Withheld
adjective

Old English with-haldan, to hold-back — past-participle of withhold. As a color modifier, withheld implies a hushed-and-pulled-back-and-not-fully-given quality where the hue carries the visual register of intentionally-restricted-and-reserved color-presentation. Sits at the hushed-and-restrained end of the grid, parallel to restrained and modulated in usage.

Freshet
noun

A sudden flood of fresh water — particularly the spring runoff of melting mountain snow into rivers. Freshet color refers to a freshet-swollen mountain river in late April: a soft, slightly cool deep blue-white with the optical complexity of snowmelt-suspended sediment.
