What does abstract painting mainly emphasize? What kind of abstraction is good?

The original meaning of the word abstraction means that people abandon the representation factors of things and extract the essential factors in cognitive thinking activities. Applied to the field of fine arts, there are concepts such as abstract art, abstractism and abstractism. Generally speaking, abstract art is a specific artistic trend of thought and genre concept in modern western art (it can be seen that this concept does not cover the art with "abstract factors", "abstract techniques" and "abstract style" in traditional art). In practical application, abstract art has a wide meaning, which can be opposite to figurative art, and generally refers to various artistic phenomena with abstract characteristics in modern western art, but the meaning of abstraction and abstraction is narrow, especially abstract thoughts and schools. On the whole, modern abstract art in the 20th century is a rebellion against the western tradition of imitating natural art, which opposes the objective description of natural images and advocates abstract analysis and expression. Broadly speaking, modern abstract art includes two types: the first one is abstracted from natural images, forming an abstract artistic image that has some connection with natural images; The second category is abstract, not based on natural images, and consists of pure forms. Abstract art in a narrow sense, that is, abstract thoughts and schools, is the second type. It denies depicting concrete objects, and it is not based on natural objects. It only uses the basic painting language and formal factors to create pure abstract painting, so as to express some spiritual content or aesthetic experience such as emotions and ideas. Generally speaking, abstract painting is a kind of painting that has little or no similarity with natural objects, but has a strong form. However, in some people's eyes, abstraction is an unsightly thing. Abstract decorative paintings enhance the sense of space. In the past, many families did not pay attention to putting decorative paintings indoors, which was considered redundant. Abstract painting has always been regarded as a difficult art, but it can make the finishing point in a family with modern decoration style. Although many people can't understand the content of painting, they are deeply infected by it, so abstract painting as decorative painting is the best choice for more and more people.
