<span>The Mona Lisa has many principals of art found within it. One is contrast. As you look at the painting, colors in the background are much lighter in tone than the foreground. The foreground uses darker colors, giving a more serious feel to the subject matter. Another principle found in the Mona Lisa is proportion. When viewing the painting, the Mona Lisa is much larger that the landscape items behind her. This proportion draws the eye to the body of Mona Lisa, as she is the main subject of the painting. Lastly, we find the principle of unity throughout the painting. All of the colors blend together with little contrast, giving a monochromatic feel to the painting, with little to distract the viewer's eye.</span>
