The paper describes the JHK colors of late-type stars which were investigated as part of a survey of South Galactic Cap (b less than 30 deg) Infrared Astronomy Satellite (IRAS) sources selected on the basis of their 12/25 micrometer flux ratios as high mass-loss candidates. Near-infrared two-color diagrams provide an effective technique for distinguishing between various groups of late-type stars. Such diagrams are also useful in indicating which stars are likely to be peculiar and worthy of more detailed study. The late-type stars isolated by this survey comprise 61 Mira variables (3 of which are carbon stars with very thick shells), 3 young stellar objects, 4 interacting binaries, 2 semi-regular carbon variables and 154 oxygen-rich giants.
