Imagery & Provenance意象与出处

Solar term

冬至 · Winter Solstice — "蚯蚓结，麋角解，水泉动。"

Imagery

“zǐkuàng” is the resinous lac insect dye — a red-purple pigment. A deep, slightly murky violet-red.

Origin

Lac dye gives a purple-red that sits between crimson and violet. As Winter Solstice’s combining colour it closes the year’s darkest day at the term’s floor: four pinks from silver to a dye-thick purple, the sun now starting its return.
