Description:
We analyze the internal optical colors of a complete sample of
I814<24mag early-type and spiral galaxies from the northern and
southern Hubble Deep Fields (HDF). The subset of galaxies in the
HDF-North are also investigated in the near-infrared using NICMOS
photometry. We compare the central (inner 5% radius) colors of those
spirals with clearly visible bulges with the integrated colors of
ellipticals in our sample.
