We report JHK (1.2, 1.6, and 2.2 micron) photometry for 23 asteroids of various spectral types. All of the TRIAD asteroid classes were sampled. The C and S classes have distinct, infrared color domains. Most R-class asteroids fall within the S-color domain and the observed M asteroids fall within the C-color domain. The E asteroids have neutral colors. Asteroid 446 Aeternitas was discovered to have an unusual J-H color (0.88 mag).
