This is a beautiful painting of a rainbow over tropical islands. The clouds make the little area of sky that is blue make it really pop and be noticeable. The rainbow adds vibrant color where there is no color. There is space in between the mountains that makes the mountains more obvious. Value is obvious when you look at how light some of the mountains are and how dark some of them are. There are many differences stressed in this artwork. All of the color and values really make the artwork show the principle of Emphasis.
