Answer:
Vincent van Gogh
Step-by-step explanation:
Expressionism came as a response to Positivism and proposed a new style of art where mere observation and representation of the world as it is is left out, in contrast to Naturalism and Impressionism. The world must be represented according to the artist's eyes.
One of the forerunners and main representatives of this movement was the Dutch painter Vicent Van Gogh. Van Gogh intended to represent the world and its natural beauty through the colors that for him represented the main element of painting. One of his most famous paintings is "Starry Night" where he portrays the night with striking colors.
