text: Typically, one is interested in coloring a graph so that no two adjacent vertices have the same color, or with other similar restrictions.
text: It should be distinguished from the chromatic number of G, the minimum number of colors needed to color the vertices so that no two adjacent vertices have the same color; the ordering which determines the coloring number provides an order to color the vertices of G with the coloring number, but in general the chromatic number may be smaller.
text: the graph’s vertices with colors such that no two vertices sharing the same edge have the same color.
