Hue is basically the term for the different base colors (red,blue,yellow,ect…). The top picture is an example of a color wheel portraying the 12 most basic hues. The bottom is a piece that uses different hues very effectively, most specifically yellow and blue. Van Gogh uses yellow and blue in a complementary way to make the piece very pleasing to the eye, as well as these colors (the cool blue and the washed out yellow) providing a sense of calm. Using hues together in certain ways are very important because they can set the overall mood for a piece easily.
