Abstract: A simple necessary and sufficient condition is given for the vertices of a graph, planar or not, to be properly four-colorable. This criterion involves the notion of an ``even'' triangulation of $ {S^3}$ and generalizes, in a natural way, a corresponding criterion for the three-colorability of planar graphs.
