We determine the correlation between spectral and morphological type for distant galaxies, defined by optical - near-infrared colors and image structure. As a point of departure, rest-frame colors of field galaxies observed to redshifts of 0.35 are shown to follow the trend in the UVK plane seen by Aaronson (1978) for local galaxies. Correlations are found between the deviations from this trend and absolute magnitude, compactness, and surface brightness. This works provides the foundation for investigations of galaxy structure at cosmologically interesting distances (Bershady, 1992).
