Fauvism is a modern painting trend that prevailed in France from 1898 to 1908. Although there is no clear theory and program, it is the result of a certain number of painters' active activities in a certain period, so it can also be regarded as a painting school.

Fauvism painters are keen on using bright and heavy colors, and often use pigments directly extruded from paint tubes to create strong picture effects with straightforward and extensive brushstrokes, which fully shows the expressionist tendency of pursuing emotional expression.

Fauvism continues the exploration of post-impressionist Van Gogh, Gauguin, Cezanne and others, and pursues more subjective and intense artistic expression. The painting style no longer pays special attention to perspective and light and shade, abandons the traditional relationship between perspective and light and shade, and adopts a flatter composition, with strong contrast between light and shade and pure realism, adding one's own feelings.

It has had an important influence on the development of western painting. They absorbed the expression techniques of oriental and African art, paid attention to creating a sparse artistic conception different from western classical painting, and had an obvious tendency of freehand brushwork.

Some people think that barbarism is part of a broad expressionist movement. Others think that Fauvism is not an artistic movement, but a short stage in the artistic career of Matisse and others, a stage that pays special attention to the expression of lines and colors and is not bound by any procedures.

Matisse later recalled: "For me, the beast period was an experiment of painting tools, and I had to create an expressive and meaningful way to blend blue, red and green side by side."

I hope it can help you solve the problem.
