Steady Murk Peacock

Old English stede, place, position — drifted to mean firm and unmoving. Used as a color modifier since the seventeenth century for hues that read as reliable rather than dramatic. Steady gray, steady green: moderate saturation combined with optical calmness. Sits in the crisp-bucket center alongside settled.

Old Norse myrkr, darkness-or-obscurity. As a color modifier, murk implies a clouded-and-dim-and-obscured quality, the visual register of fen-and-bog-and-tarn-murk hand-clouded-and-dim-and-obscured fen-and-bog-and-tarn-and-marsh murky-and-clouded-and-dim-and-obscured surfaces under fen-and-bog-and-tarn-and-marsh peat-stained-and-clouded-and-dim swamp-and-fen-light. Sits at the modifier-and-mood end of the grid, parallel to gloom and pall in usage.

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.
