We describe the automation of the calculation of perturbative unitarity constraints including scalars that have colour charges, and its release in SARAH4.14.4. We apply this, along with vacuum stability constraints, to a simple dark matter model with colourful mediators and interesting decays, and show how it leads to a bound on a thermal relic dark matter mass well below the classic Griest-Kamionkowski limit.
