Abstract: In this thesis, we study the chromatic numbers of suborbital graphs for Hecke groups H(p2) and H(p3). We decompose each suborbital graph into disjoint isomorphic subgraphs and show that each subgraph is homomorphic to the Farey graph. Finally, we show that each suborbital graph has chromatic number 2 or 3.
