Imagery & Provenance意象与出处
Solar term
夏至 · Summer Solstice — "昼晷已云极,宵漏自此长。"
Imagery
A heavy, dark red named in the oldest dye vocabulary — the deepest crimson the term reaches.
Origin
Summer Solstice ends at the bottom of its red range. A full year’s daylight is at its peak and the colour is at its darkest — a paradox the term holds: the brightest day closes on the deepest crimson, the turning point of the year.
System
B Solar-term sets
Source
Wei Yingwu, “Escaping the Heat by the North Pool at the Summer Solstice”. (combining colour of 夏至.)
