Impressionist paintings are usually characterized by visible brushstrokes, open composition, emphasis on light in its changing qualities, ordinary subject matter, inclusion of movement as a crucial element of human perception and experience and unusual visual angles. Colors are generally applied side-by-side with as little mixing as possible to create a vibrant surface. In pure impressionism, use of black paint is generally avoided. Impressionist paintings do not exploit the transparency of thin paint films; in fact impressionist painting is typically opaque. The play of natural light is emphasized to produce effects. A common practice in case of outdoor paintings is that, the shadows are boldly painted with sky blue color to add a sense of freshness and openness to the painting.
