What is the reason why the traditional colored porcelain "plain tricolor" is called "plain" because it doesn't use any color?
There is no need to use red in the Ming and Qing Dynasties. Among the colorful colored porcelain, there is a kind of colored porcelain decorated with green, yellow, purple and white. Because there is no bright and lively red in the color of this porcelain, it is called "plain tricolor". Plain color, originally refers to the simple color, not gorgeous, plain and clean meaning.
