  We classify the hadron light-cone wave-function amplitudes in terms of parton
helicity, orbital angular momentum, and quark flavor and color symmetries. We
show in detail how this is done for the pion, $\rho$ meson, nucleon, and delta
resonance up to and including three partons. For the pion and nucleon, we also
consider four-parton amplitudes. Using the scaling law derived recently, we
show how these amplitudes scale in the limit that all parton transverse momenta
become large.
