What's the difference between Zhu and Bai?

"Zhu Wen" means that the printed words are vermilion, and "Bai Wen" means that the printed words are white.

In fact, "Zhu" and "white" refer to colors, "Zhu Wen" refers to printed scarlet letters, and "Bai Wen" refers to printed white characters. Judging from the current research results, China's early seals are mostly white, and the lines in white are mostly horizontal and vertical, which has an ancient and clumsy atmosphere. Most of the "sealing mud" we talked about before is similar to white printing. Zhu Wen mostly appeared between the Six Dynasties and the Tang and Song Dynasties, and gradually developed after the Yuan Dynasty. Relatively speaking, his lines are more rounded and his style is more elegant.
