Starched Cardoon

#64d5b5
Notes

Starched Cardoon (#64D5B5) is a true teal 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 (163°, 57%, 61%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Starched
adjective

Old English stercan, to stiffen — past-participle of starch. As a color modifier, starched implies a clear-and-stiff-and-formal quality, the crisp color of Edwardian-period formal-evening-shirt-and-collar starched-and-pressed dress-attire. Sits at the crisp-and-finished end of the grid, parallel to pressed and ironed in usage.

Cardoon
noun

Cynara cardunculus, the Mediterranean thistle — relative of the globe artichoke (C. cardunculus var. scolymus) — with deeply lobed silver-green foliage and architectural form. The color refers to mature cardoon foliage in a kitchen garden: a soft, slightly cool silver-green-blue with the matte finish of large pinnately lobed leaves.
