WebMay 22, 2024 · 4. Method to Color a Graph 1. Arrange the vertices of graph in the same order. 2. Choose the first vertex and color it with the first color. 3. Then choose next vertex and color it with the lowest numbered color that has not been colored on any vertices which is adjacent to it. 4. WebSolution: In the above cycle graph, there are 3 different colors for three vertices, and none of the adjacent vertices are colored with the same color. In this graph, the number of vertices is odd. So. Chromatic number = 3. Example 2: In the following graph, we have to determine the chromatic number.
