The authors give an alternative construction of umbral chromatic polynomials. They develop an umbral interpolation formula which generalizes the classical Newton forward interpolation formula. The authors also explain how their new approach relates directly to the addition/contraction tree of a given graph, and results in a simple algorithmic procedure for computing the umbral chromatic polynomial.
