The power graph Γ G of a finite group G is the graph whose vertex set is the group, two distinct elements being adjacent if one is a power of the other. We investigate the chromatic number χ (Γ G) of Γ G. A characterization of χ (Γ G) is presented, and a conjecture in Mirzargar et al.(2012) is disproved. Moreover, we classify all finite groups whose power graphs are uniquely colorable, split or unicyclic.
