We discuss extensions of the standard model that contain a color triplet scalar field and perhaps other fields. We show that, for a range of temperatures, there is a phase where the free energy is minimized by the color triplet scalar having a vacuum expectation value, spontaneously breaking color. At very high temperatures and at lower temperatures color symmetry is restored. The breaking of color in this phase is accompanied by the spontaneous breaking of B-L if the color triplet scalar Yukawa couples to quarks and/or leptons.
