Why did Henri Matisse paint woman in purple coat?

Henri Matisse painted "Woman with a Purple Coat" in 1937 to explore bold colors and expressive forms, reflecting his interest in Fauvism. The vibrant hues and simplified shapes emphasize the emotional experience of the subject rather than realistic representation. This work showcases Matisse's innovative approach to portraiture, focusing on the interplay of color and light to convey mood and character.
