It is argued that color transparency in quasielastic scattering of electrons and hadrons on nuclei is possible only due to Fermi motion. We found a strong dependence of nuclear transparency on Bjorken x in (e,e’p); it is close to the Glauber model expectations at x>1, but increases and even exceeds one at x<1. It is argued that color transparency is accompanied by large longitudinal momentum transfer to nuclear matter during the passage of the small size wave packet.
