本文介绍了QCD（SU（Nc））色求和计算的Mathematica软件包。可以执行QCD中出现的任何颜色振幅的颜色收缩，并且该包使用与在纸上书写颜色结构的方式非常相似的语法。它还支持颜色向量和基的定义，并为此类颜色张量定义了标量积等特殊函数。
A Mathematica package for color summed calculations in QCD (SU(Nc)) is presented. Color contractions of any color amplitude appearing in QCD may be performed, and the package uses a syntax which is very similar to how color structure is written on paper. It also supports the definition of color vectors and bases, and special functions such as scalar products are defined for such color tensors.
