Finding compact integrand representations of QCD amplitudes requires convenient integral bases. In this seminar I will demonstrate how the infrared divergences of some D-dimensional Feynman integrals can be regulated using special choices of numerators. These choices are inspired by the existing four-dimensional local integrand structures due to Arkani-Hamed et al, valid only in the planar limit of maximally supersymmetric N=4.
