Level Glazed Peacock

Latin libella, small-balance / level-tool — sharing root with libra (balance). As a color modifier, level implies a clear-and-horizontal-true quality where the hue carries the visual register of gravity-perpendicular-and-perfectly-horizontal surface. Sits at the crisp-and-balanced end of the grid, parallel to plumb and flat in usage.

Old English glæs, glass. As a color modifier, glazed implies a fired-pottery-glaze-and-glass-coating quality, the visual register of Stoke-on-Trent-and-Italian-Maiolica-glazed hand-applied-and-fired ceramic-and-pottery-and-tile-glaze Stoke-on-Trent-and-Italian-Maiolica glazed-pottery surfaces under Stoke-on-Trent-and-Italian-Maiolica hand-glazed pottery-and-tile workshop-light. Sits at the modifier-and-texture end of the grid, parallel to gloss and enameled 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.
