Imagery & Provenance意象与出处

Solar term

清明 · Pure Brightness — "清明时节雨纷纷，路上行人欲断魂。"

Imagery

From Li He’s frontier poem — “the rouge on the frontier congeals into night’s purple”. A blackened violet that reads as near-black.

Origin

The line describes blood-red darkening into the purple of a northern night. As the combining colour it carries Pure Brightness to its floor — the four violets have travelled from reed to dye to rank to darkness, and the term ends in a colour almost indistinguishable from black.

System

Source

Du Mu, “Pure Brightness” — “a rain falls thick; the traveller on the road is sick at heart.” (combining colour of 清明.)
