Colour: a computer program for QCD colour factor calculations

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.
