Abstract

"National color" is tempered from the process of historical civilization, and modern times.

and Southern Dynasties advocated blue, which was bright and flying; the Song Dynasty advocated
"preserving natural principles and removing human desires", fresh and elegant Green has become
the mainstream; in addition, yellow, which symbolizes imperial power, and the majestic Chinese
red have always been the national colors that will never fade in the hearts of the Chinese nation.
