Practical Gable Peacock

Greek praktikós, practical — adjectival suffix -al. As a color modifier, practical implies a clear-and-purpose-fit-and-everyday quality where the hue carries the visual register of Shaker-and-Quaker utilitarian-and-functional everyday-life craft. Sits at the crisp-and-functional end of the grid, parallel to functional and workmanlike in usage.

Old French gable, triangular-end-of-pitched-roof. As a color modifier, gable implies a triangular-end-of-pitched-roof quality, the visual register of English-and-Tudor-and-Pennsylvania-Dutch-gable hand-built triangular-pitched-roof gable-and-dormer architectural surfaces under English-and-Tudor-and-Dutch gable-end light. Sits at the modifier-and-architecture end of the grid, parallel to eave and truss 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.
