And there is clearly no hope of coloring this graph with only one color. 5 A general result We can also prove a useful general fact about colorability: Claim 1 If all vertices in a graph G have degree ≤ D, then G can be colored with D +1 colors. Notice that this is only an upper ... In graph theory, graph coloring is a special case of graph labeling; it is an assignment of labels traditionally called "colors" to elements of a graph subject to certain constraints. In its simplest form, it is a way of coloring the vertices of a graph such that no two adjacent vertices are of the same color; this is called a vertex coloring. Similarly, an edge coloring assigns a color to each edge so tha… Webdifferent colors. A graph is k-colorableif there is a proper k-coloring.
