The renormalizable coloron model is the minimal extension of the standard model color sector, in which the color gauge group is enlarged to SU(3) sub(1)c x SU(3) sub(2)c. In this paper we discuss the constraints on this model derived from the requirements of vacuum stability, tree-level unitarity, and electroweak precision measurements from LHC measurements of the properties of the observed Higgs-like scalar boson and from LHC limits on additional Higgs-like bosons decaying to dibosons. The combination of these theoretical and experimental considerations strongly constrains the allowed parameter space.
