A photometric system using a broad-band color combined with a line strength index is employed to distinguish age differences from metallicity differences between the bulges and disks of S0 galaxies. A color difference independent of metallicity changes of about delta (U-V) = 0.10 is found for the sample of galaxies observed here. Several S0 galaxies have absorption line strengths that indicate the disks are as metal-rich as the most luminous elliptical galaxies. It is concluded that the disks of S0 galaxies are probably younger than the bulges, but the distinction between a younger turnoff and residual star formation cannot be made.
