Webdefinition of chromatic number to oriented graphs, we define the oriented chromatic number of an oriented graph G~ to be the minimum number of vertices in an oriented graph H~ for which there exists a homomorphism of G~ to H~. We denote this number by ˜ o(G~). The oriented chromatic number of an oriented graph G~ can also be defined as …

Assigning distinct colors to distinct vertices always yields a proper coloring, so The only graphs that can be 1-colored are edgeless graphs. A complete graph of n vertices requires colors. In an optimal coloring there must be at least one of the graph's m edges between every pair of color classes, so If G contains a clique of size k, then at least k colors are needed to color that clique; in other wor…
