  We have developed a new non-gray theory of the evolution, spectra, and colors
of extrasolar giant planets (EGPs) and brown dwarfs that reveals their exotic
nature and uniqueness. We have discovered that the fluxes of such objects for
T$_{eff}$s from 1300 K to 100 K can be spectacularly higher in the near
infrared bands than black body values and that their infrared colors are
anomalously blue. As a consequence, EGPs and brown dwarfs reside in hitherto
unoccupied realms of the H--R diagram and may be more easily found with current
and planned telescopes than previously imagined.
