Using stars from the Bright Star Catalog, supplemented by cool dwarf stars from the Gliese catalog, that were detected by IRAS, the authors define empirically the median intrinsic visual-to-infrared color indices for "normal" stars as a function of IRAS wavelength (at 12, 25, 60, and 100 μm), spectral type (between O5 and M8), and luminosity class (all classes between I and V). These indices are presented graphically and in tabular form. Anomalously red stars are dicussed. Two otherwise undistinguished F giant stars are found with significant excesses at 12 μm. Be stars differ markedly from non-emission B stars in their V-[12] indices due to contamination of the former by free-free emission. Both B and Be stars show large dispersions in V-[25] colors that the authors associate with the heating of local, but strictly interstellar, dust clouds by some of the non-emission B stars. The derived sequences of stellar colors are closely approximated by either simple blackbody predictions or by model-atmosphere calculations.
