('0 Supercolor*

We propose new types of theories which combine supersymmetry and some new strong interaction which we generically refer to as supercolor. In some cases which we discuss, supercolor is identical with the familiar Technicolor. These theories are natural. They explain the scale of weak interactions and they do not require any unnatural adjustments. They possess naturally light scalars which give mass to ordinary quarks and leptons. Naturalness imposes strong constraints on the U(1) gauge structure of the theory. These constraints appear not to be satisfied by the electro-weak hypercharge. If this is true then, the symmetry of the world at energies above-1 TeV cannot be standard SU3Cx SU2Lx U(l)y with only ordinary families.
