Pellucid Balm Peacock

#28576b
Notes

Pellucid Balm Peacock (#28576B) is a deep cyan 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 (198°, 46%, 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. For a confident two-color system, pair it with its complementary orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Pellucid

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.

Latin balsamum, aromatic-resin-and-soothing-oil. As a color modifier, balm implies an aromatic-resin-and-soothing-oil-and-lemon-balm quality, the visual register of apothecary-balm-and-lemon-balm hand-aromatic-resin-and-soothing-oil-and-lemon-balm apothecary-balm-and-lemon-balm-and-Tudor-still-room balm-and-aromatic-resin-and-soothing-oil surfaces under apothecary-balm-and-lemon-balm-and-Tudor-still-room Tudor-still-room-and-monastic-physic-garden apothecary-and-still-room-light.

Peacock
noun

Pavo cristatus, the Indian peafowl whose male displays the most elaborate sexual ornament in birds — a fan of two-meter eyespotted tail feathers in iridescent blue-green. The color is structural, not pigmented: created by interference patterns in the feather barbules. Peacock blue refers to the dominant body color: a saturated, slightly muted teal-blue with the optical depth of structural color. Cooler than persian, warmer than sapphire.
