Cloaked Glaucium

#213556
Notes

Cloaked Glaucium (#213556) is a deep azure 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 (217°, 45%, 23%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

noun

The genus Glauciumhorned poppy, Mediterranean coastal-dune annuals with silver-blue foliage and yellow or orange flowers. The genus name traces to the same Greek glaukos as glauque (gray-blue-green).
