Calculations involving the SU(3) structure of QCD are typically performed using socalled trace bases or color flow bases for decomposing color structure. While these spanning sets have some simplifying properties, the fact that they are overcomplete and non‐orthogonal becomes a major obstacle for calculations involving many partons. In this talk I will describe how to use group invariants to perform color space calculations instead, and I will argue that this ‐‐‐ once a sufficient set of invariants and an efficient implementation is at hand ‐‐‐ may well be superior.
