  We calculate expressions for the quadrupole moments of nonstrange baryons in
which the number of QCD color charges is N_c. Using only the assumption of
single-photon exchange, we obtain 4 relations among the 6 moments, and show how
all of them may be obtained from Q_{\Delta^+ p} up to O(1/N_c^2) corrections.
We compare to the N_c=3 case, and obtain relations between the neutron charge
radius and quadrupole moments. We also discuss prospects for the measurement of
these moments.
