We present efficient algorithms to calculate the color factors for the SU(N) gauge group and to evaluate γ traces. The aim of these notes is to give a self-contained, proved account of the basic results with particular emphasis on color reductions. We fine tune existing algorithms to make calculations at high loop orders possible.
