The 13-color photometry of a representative sample of 86 Be and shell stars observed at the San Pedro Martir Observatory (Mexico) is presented. The data are separated into early-type stars (B0-B5), late-type stars (B6-B9), and supergiant and peculiar B stars. For the highly variable Be and shell stars observed, a report of their photometric properties is given. To test the average characteristics of the Be stars, the classification scheme and the 140 bright Be stars of Jaschek et al. (1980) are used for comparison. Jaschek and co-workers separated the Be stars into five groups according to spectroscopic criteria. A table giving a description of their spectroscopic groups is included. It is pointed out that since a large number of Be and shell stars are variable, the reported magnitudes and colors correspond to the 'averaged' values of the observations.
