Fresh Hydrangea

#2b8289
Notes

Fresh Hydrangea (#2B8289) 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 (184°, 52%, 35%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Fresh
adjective

Old English fersc, unsalted / not stale — sharing root with German frisch. As a color modifier, fresh implies a clear-and-newly-applied quality where the hue carries the just-emerged visual register. Sits at the crisp-and-clean end of the grid, parallel to crisp and new in usage.

Hydrangea
noun

The genus Hydrangea — particularly H. macrophylla, whose flower color depends on soil pH (acidic = blue, alkaline = pink). The color refers to a blue-bloom H. macrophylla in acidic-soil garden: a saturated, slightly cool deep blue-violet with the matte finish of clustered four-petaled florets.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
