Dependable Hydrangea

#64a2cf
Notes

Dependable Hydrangea (#64A2CF) is a true azure with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (205°, 53%, 60%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Dependable
adjective

Latin dē-pendere, to hang from — adjectival suffix -able. As a color modifier, dependable implies a clear-and-trustworthy-and-consistent quality where the hue carries the visual register of consistently-performing-and-counted-on design-element. Sits at the crisp-and-honest end of the grid, parallel to reliable and trustworthy 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.
