Van Gogh´s choice of color in Starry Night has been much debated, particularly the dominance of yellow in this and other late works. Some believe van Gogh may have been suffering from lead poisoning or a type of brain disease and that this explains his strange use of color in later paintings.
Van Gogh's use of white and yellow creates a spiral effect and draws attention to the sky. Vertical lines such as the cypress tree and church tower softly break up the composition without retracting from the powerful night sky depicted in Starry Night.
Vincent van Gogh´s choice of dark blues and greens were complemented with touches of mint green showing the reflection of the moon. The buildings in the centre of the painting are small blocks of yellows, oranges, and greens with a dash of red to the left of the church. The dominance of blue in Starry Night is balanced by the orange of the night sky elements.
Van Gogh paints the rich colors of the night and this corresponds with the true character of this Starry Night, whereby colors are used to suggest emotion.
