Graph Coloring

A coloring of a simple graph is the assignment of a color to each vertex of the graph so that no two adjacent vertices are assigned the same color.

Below are two simple graphs. Color each of the graphs according to the instructions. Make sure that in each situation any vertices that are connected are not the same color.


Color each graph below with as many colors as you can.

Now color each one in a different way.

Finally try to color the graph with the least number of colors possible.
