For a dodecahedron, at least 3 different colors are required, as a dodecahedron cannot be properly colored in less than 3 colours. It is advisable to draw the planar graph of a a dodecahedron when planning the 3-edge coloring. “It is always quite puzzling to try to make use only 3 colors of paper with no two units of the same color touching. Each unit corresponds to an edge of the planar graph, so this is equivalent to a proper 3-edge-coloring of the polyhedron.” (T.Hull, 2006)
