Lush Caraway Cobalt

#2f53ab
Notes

Lush Caraway Cobalt (#2F53AB) 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 (223°, 57%, 43%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Lush
adjective

Middle English lush, possibly from lascious, lascivious — a word that drifted from sensual ripeness toward visual abundance. Used as a color word since the eighteenth century for the saturated greens of well-watered foliage and the deep saturated jewel tones of velvet upholstery. Used across the deep and bold buckets where the hue is simultaneously dark and vivid.

Caraway
modifier

Arabic al-karawiyā, aromatic-rye-bread-seed. As a color modifier, caraway implies an aromatic-rye-bread-and-Central-European-seed quality, the visual register of Bavarian-and-Central-European-caraway hand-aromatic-rye-bread-and-Central-European-seed Bavarian-and-Central-European-caraway-and-Czech-and-Hungarian-rye caraway-and-aromatic-rye-bread surfaces under Bavarian-and-Central-European-caraway-and-Czech-and-Hungarian-rye Bavaria-and-Bohemia-and-Hungary Central-European-rye-light. Sits at the modifier-and-flavor end of the grid, parallel to cumin and anise in usage.

Cobalt
noun

Element Co, atomic number 27 — German Kobold, goblin, named by miners who found the metal interfered with smelting silver ore. Cobalt blue is the cobalt-aluminate pigment introduced by Louis Jacques Thénard in 1802: a saturated, slightly green-shifted deep blue with the matte finish of mineral pigment in oil. Cooler than ultramarine, warmer than prussian, with the painter's weight of a pigment used by Renoir, Van Gogh, and Cézanne.
