Aged Anchusa

#315a5c
Notes

Aged Anchusa (#315A5C) is a deep 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 (183°, 30%, 28%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

Aged
adjective

The past participle of age — used as a color modifier since the seventeenth century for hues that have changed through time. Aged paper, aged copper: low-to-moderate saturation combined with the optical impression of patina. Sits at the hushed-bucket alongside weathered and antique.

Anchusa
noun

The genus Anchusa — Mediterranean borage-family perennials with saturated deep-blue flower spikes used in Renaissance European herbal medicine. The color refers to a fresh A. azurea (Italian bugloss) flower spike: a saturated, slightly cool deep blue with the matte finish of small five-petaled forget-me-not-style flowers.
