We investigate the co-evolution of galaxies and black holes at the epoch of maximum growth, comparing normal galaxies and active galactic nucleus (AGN) host galaxies at z 1, using new, highly accurate photometric redshifts from the MUSYC medium-band survey in the Extended Chandra Deep Field-South (ECDF-S) and correcting for reddening using rest-frame near-infrared colors and SED fitting. The distribution of AGN host galaxies in color space is identical to that of normal (inactive) galaxies, at least for log M > 10 MSun, where the sample is complete. After dust correction, few AGN hosts lie in the green valley, unlike the situation at z˜ 0. Instead, at z˜1, AGN activity is roughly evenly split between two modes of black hole growth: the first in passively evolving host galaxies, which may be heating up the galaxy's gas and preventing future episodes of star formation, and the second in dust-reddened young galaxies, which may be ionizing the galaxy's interstellar medium and shutting down star formation.
