We investigate the host galaxy colors of X-ray detected AGN in the Extended Chandra Deep Field South.We have conducted deep medium-band imaging with the Subaru telescope, in 18 filters from 427 nm to 856 nm, of the MUSYC survey field. We detect 80,000 galaxies to equivalent magnitude R 27 mag, of which approximately 1,000 are X-ray-detected AGN observed with Chandra and XMM. Combining the Subaru data with optical, IR data and IRAC photometry we obtain photometric redshifts using EAZY, a fast public photometric redshift code, in the range 0
