B) Initialize the remaining vertices. C) Declare a temporary array to store the available colors. D) Assign color to the remaining vertices. Print the solution. End Example Code WebGraph coloring is nothing but a simple way of labelling graph components such as vertices, edges, and regions under some constraints. In a graph, no two adjacent vertices, adjacent edges, or adjacent regions are colored with minimum number of colors. This number is called the chromatic number and the graph is called a properly colored graph.
