Practical Year 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 English gēar, year. As a color modifier, year implies an annual-cycle quality, the visual register of agricultural-and-pastoral yearly-rhythm seedtime-and-harvest seasonal-cycle pasture-and-arable surfaces under year-long pastoral-and-agricultural sky. Sits at the modifier-and-time end of the grid, parallel to cycle and phase 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.
