What word does Qingming Baba use to describe his color?

Qingming Baba in southern Anhui: one of the specialties in Xuancheng and other places, also known as Haozi Baba. Every year during the Qingming Festival, Artemisia annua, also known as Artemisia capillaris, germinates in March and has a circle of green white hair. People pick it, wash it, mix it with glutinous rice, and then grind it into powder as dough.

Qingming Festival is coming, and the folk tradition is to eat that dish Baba. Express condolences to our ancestors.
