Pellucid Cardoon

#216a59
Notes

Pellucid Cardoon (#216A59) is a deep teal 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 (166°, 53%, 27%) 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

Pellucid
adjective

Latin pellūcidus, transparent — derived from per-lūcēre (to shine through). As a color modifier, pellucid implies a clear-and-translucent quality where the hue reads with optical clarity and minimal turbidity. Sits at the crisp-and-clear end of the grid, parallel to lucid and translucent 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.
