We discuss the ground-state baryons $N$, $\Lambda$, $\Sigma$, $\Xi$, $\Delta$, ${\Sigma }^{*}$, ${\Xi }^{*}$, and $\Omega$ in a quark model with flavor-independent confinement and color hyperfine interactions. We include the effects of wave-function distortions for unequal quark masses as well as interband mixing via the hyperfine interactions and find good agreement with the observed masses.
