  We present a software that automatically generates a multiplet color basis
for general $2 \to n$ processes in quantum chromodynamics (QCD). The
construction process is guided by the decomposition of the corresponding
$\mathrm{SU}(N_c)$ representation into a direct sum of irreducible
representations. The projectors of these irreducible multiplet states are then
used to construct a minimal, linearly independent basis. The software achieves
highest efficiency through a combination of the Z3 satisfiability modulo
theories solver and the symbolic manipulation program FORM. The resulting color
basis enables the analytical execution of involved QCD calculations that
require color decomposition.
