The Miao in Southeast Guizhou was labeled as"black Miao"or"Green/Blue Miao"in the historical records of the Ming and Qing dynasties. The linguistic evidence in their mother tongue reveals that"blue"and"green"are their preference while"red"and"yellow"are the colors they dislike,and that"red"even symbolizes"poverty"and"disaster".This paper holds the view that this color aesthetic is molded by the ecological environment they live in,the way of their production,and their religious belief. The aesthetic preference reflects that the harmony of man and nature is the highest aesthetic criterion for local Miao people,so it is deeply significant in economic aesthetics,which is far beyond time and space.
