WebA coloring using at most k colors is called a (proper) k–coloring, and a graph that can be assigned a (proper) k–coloring is k–colorable. For example, consider the following graph, It can be 3–colored in several ways: Please note that we can’t color the above graph using two colors, i.e., it’s not 2–colorable.
