Cousins VRI photometry is presented for 26 stars with continuous scans by Gunn and Stryker. This photometry is combined with literature data and a few unpublished results to critique synthetic colors from the Gunn-Stryker scans. For V - R, it is found that all pertinent results are consistent at the several-mmag level. For R - I, however, systematic differences are found which are most simply interpreted as a declination effect in the Gunn-Stryker scans. In addition, it is found that the Gunn-Stryker synthetic colors are unexpectedly noisy, with sigma per datum of about 0.02 mag. It is suggested that future users of the Gunn-Stryker data keep both these effects in mind.
