There is a certain kind of art behind the graph coloring and the four color theorem. I mean, of course it is because there is actual color being used in a math problem. Math, where usually you have to add and subtract numbers. This painting above, created by Piet Mondrian, does not exactly represent the four color theorem. There are edges touching that share the same color, so that of course would not work in the color theorem. But this painting was done in 1930, and the four color theorem wasn’t approved until 1976. When you compare the oil painting to an actual four color theorem problem, at first glance you might jus consider both of them to be pieces of abstract art. Of course once you take a closer look, you can see that math problem behind the picture on the right. “In mathematics, the four color theorem, or the four color map theorem, states that, given any separation of a plane into contiguous regions, producing a figure called a map, no more than four colors are required to color the regions of the map so that no two adjacent regions have the same color.” So maybe Mondrian wasn’t trying to achieve the four color theorem with his oil painting, but he was getting close. There is math everywhere, even in art. Or sometimes the math problem turns into the art.
