Take your pick.

Please edit: the second instance of using the word 'other' should be changed to 'besides' so that you may avoid redundancy, and your sentence won't sound repetitive either. And how about some ending punctuation on that last sentence of yours, Pal?

Indeed, there is in art. In the art field, a supremacist is a person that uses a style of art called "Suprematism". This is an art movement started in Russia by an artist named Kazamir Malevich. The art focuses on basic geometric forms, using a limited amount of color and is referred to, as abstract art.

Contemporary artists may use this style combined with other Russian styles and artists come in all colors.
