Disciplined Zen Peacock

Latin disciplīna, teaching / training — past-participle of discipline. As a color modifier, disciplined implies a clear-and-controlled-and-careful quality where the hue carries the visual register of careful-edited-and-restrained design-decision. Sits at the crisp-and-orderly end of the grid, parallel to methodical and orderly in usage.

Japanese 禅, Zen Buddhism. As a color modifier, zen implies a stripped-down-and-meditative-Mahayana quality, the visual register of Japanese-Sōtō-and-Rinzai-Zen Zen-Buddhist hand-laid rock-garden-and-tatami-and-shōji-screen meditation-hall surfaces under Sōtō-and-Rinzai-Zen Kyoto-temple-garden meditative quiet light. Sits at the modifier-and-cultural end of the grid, parallel to tao and sufi 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.
