Aging Hydrangea

#6a8991
Notes

Aging Hydrangea (#6A8991) 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 (192°, 16%, 49%) 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

Aging
adjective

Old French aage, age — present-participle of age. As a color modifier, aging implies a hushed-and-time-deepening-and-developing quality where the hue carries the visual register of Bordeaux-and-Burgundy multi-decade gradually-aging-and-deepening wine-cellar maturation. Sits at the hushed-and-aged end of the grid, parallel to seasoning and maturing 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.
