Diaphanous Aubrieta

#a4b5d0
Notes

Diaphanous Aubrieta (#A4B5D0) is a soft 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 (217°, 32%, 73%) places it in the balanced band at a light lightness. It works as a background wash, large-area fill, or soft illustration tone. Add a darker ink of the same hue when you need type over it. For a confident two-color system, pair it with its complementary amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Diaphanous
adjective

From the Greek diaphanēs, transparent — used as a color modifier since the seventeenth century for hues with the optical translucency of fine fabric. Diaphanous white, diaphanous pink: very low saturation combined with the optical impression of light passing through. Sits at the pale-bucket alongside sheer.

Aubrieta
noun

The genus Aubrieta — Mediterranean rock-garden perennial named for the eighteenth-century French botanical illustrator Claude Aubriet. Mauve-and-blue mat-forming spring bloomer. The color refers to a fresh A. deltoidea mat at peak bloom: a saturated, slightly cool deep blue-violet with the matte finish of small four-petaled flowers covering rocks.
