Notes

Smoky Azurite (#1F4873) is a deep 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 (211°, 58%, 29%) 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.

Etymology

Smoky
adjective

An adjectival form of smoke, used as a color word since at least the fourteenth century. Smoky implies a slightly muted, slightly hazed quality — as if the color were seen through a layer of suspended particulate. Used across both deep and neutral buckets: a smoky black has slightly less density than pure black; a smoky gray has slightly less coolness than pure gray.

Azurite
noun

A copper carbonate mineral — Cu₃(CO₃)₂(OH)₂ — the natural blue counterpart to malachite, often co-occurring with it in oxidized copper deposits. Mined and ground for pigment since classical Egyptian times. The color refers to a clean azurite specimen: a saturated, slightly cool deep blue with the satin finish of crystallized secondary copper mineral. Cooler than malachite.
