A graph G = (V, E) with χ(G) ≤ 2 is called a 2-colorable graph. A couple of minutes of reflection should convince you that for n ≥ 2, the cycle C2n with 2n vertices is 2-colorable. On the other hand, C3 ≅ K3 is clearly not 2-colorable. Furthermore, no odd cycle C2n + 1 for n ≥ 1 is 2-colorable.

To study graphs as mathematical structures, we use graph labeling. Graph labeling is a way of assigning labels to vertices, edges, or faces of a graph. It can be done in various ways. Graph coloring is one of the prime methods of labeling. It is a process of assigning labels or "colors" to elements of a graph following certain constraints.
