Abstract A computer program for evaluating colour factors of QCD Feynman diagrams is presented, and illustrative examples on how to use the program to calculate nontrivial colour factors are given. The program and the discussion in this paper is based on a diagrammatic approach to colour factors. Title of program: colour Catalogue Id: ADEW_v1_0 Nature of problem In many QCD Feynman diagrams there is a need to calculate the colour factor. This program calculates colour factors fast and accurately. Versions of this program held in the CPC repository in Mendeley Data ADEW_v1_0; colour; 10.1016/S0010-4655(96)00140-3 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)
