The video tutorial explains vertex coloring and chromatic number in graph theory. Vertex coloring involves assigning colors to graph vertices such that no two adjacent vertices share the same color. The chromatic number is the minimum number of colors needed for such a coloring. The tutorial provides examples, including a null graph with a chromatic number of 1 and a connected graph with a chromatic number of 2.
