It reflects a shift in Van Gogh's style towards lighter and brighter colors compared to his earlier works. The self-portrait captures different aspects of Van Gogh's moods and physical condition, showing variations in his appearance from shabby with an unruly beard to almost elegant. The choice of a grey felt hat in the painting adds a sense of sophistication and style to the self-portrait.
