  We examine the relationship between environment and the luminosities, surface
brightnesses, colors, and profile shapes of luminous galaxies in the Sloan
Digital Sky Survey (SDSS). For the SDSS sample, galaxy color is the galaxy
property most predictive of the local environment. Galaxy color and luminosity
jointly comprise the most predictive pair of properties. At fixed luminosity
and color, density is not closely related to surface brightness or to Sersic
index -- the parameter in this study that astronomers most often associate with
morphology. In the text, we discuss what measureable residual relationships
exist, generally finding that at red colors and fixed luminosity, the mean
density decreases at the highest surface brightnesses and Sersic indices. In
general, these results suggest that the morphological properties of galaxies
are less closely related to galaxy environment than are their masses and
star-formation histories.
