 Abstractionism is a part of art.
To my mind, in general art is an expression of your mind, so that I completely accept abstractionism as a branch of art. Abstract art is purely based on your creative instincts. They may be spontaneous and innate. It is necessary to be well-educated and broad-minded person to understand the abstract paintings in-depth. I like them; I like to analyze the abstract creation of the famous painters.
The most important aspect of abstractionism is the color. It is interesting to study subtle use of colors. The abstract painters usually choose emotional and dramatic expressions to represent their imagination. They create masterpieces of abstract art with opposition, contrast colors, shades. These elements give a mystifying effect.
Abstractionism can only be created if you can imagine and feel your painting.
