In this paper, we obtain the dominator chromatic number for the Line graph of some graphs, Central graph of Line graph of Star graph and Central graph of Line graph of Double Star graph. And also we obtain the dominator chromatic number for J(S_{n}),J(C_{n}) and J(K_{1,n,n,n}) respectively.enColoringDominationDominator doloringArticle682135013582618-6470
