Instead of the usual dijet decay, the coloron may mainly decay into its own “Higgs bosons”, which subsequently decay into many jets. This is a general feature of the renormalizable coloron model, where the corresponding “Higgs bosons” are a color-octet Θ and a color-singlet φ_I. In this paper, we perform a detailed collider study for the signature of $p p \to G^{'} \to (Θ \to g g) (ϕ_{I} \to g g q \bar{q})$ with the coloron G' as a six-jet resonance. For a light φ_I below around 0.5 TeV, it may be boosted and behave as a four-prong fat jet. We also develop a jet-substructure-based search strategy to cover this boosted φ_I case. Independent of whether φ_I is boosted or not, the 13 TeV LHC with 100 fb^-1 has great discovery potential for a coloron with the mass sensitivity up to 5 TeV.
