Tidy Shag Peacock

Old English tidig, timely — drifted in modern English to mean neat, orderly. Used as a color modifier for hues that read as composed and unfussy. Tidy beige, tidy gray: moderate saturation combined with optical neatness. Sits at the crisp-bucket alongside plain and modest.

Old Norse skagg, beard / rough-hair. As a color modifier, shag implies a rough-and-shaggy-hair-or-pile quality, the visual register of Mid-Century-Modern-and-1970s-shag-rug hand-tufted-and-rough-and-shaggy wool-and-yarn-and-pile Mid-Century-Modern-and-1970s shag-rug surfaces under Mid-Century-Modern-and-1970s shag-rug interior-decoration light. Sits at the modifier-and-texture end of the grid, parallel to fuzz and fluff 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.
