CEBAF is a high-luminocity factory of virtual photons with variablevirtuality $Q^{2}$ and transverse size. This makes CEBAF, in particular afterthe energy upgrade to (8-12)GeV, an ideal facility for uncovering newphenomena, and opening new windows, at the interface of the perturbative andnonperturbative QCD. We discuss color transparency as the case for a broadprogram on electroproduction of vector mesons$\rho^{0},\,\omega^{0},\,\phi^{0}$ and their radial excitations$\rho',\,\omega',\,\phi'$ at CEBAF. We also comment on the second generation ofexperiments on color transparency in $^{4}He(e,e'p)$ scattering, which are alsofeasible at CEBAF. In 1994, we can make more reliable projections into futurebecause our understanding of the onset of color transparency has greatly beenaugmented by two experiments completed in 1993:\\ i) no effect of CT was seenin the SLAC NE18 experiment on $A(e,e'p)$ scattering at virtualities of theexchanged photon $Q^{2} \lsim 7$ GeV$^{2}$, \\ ii) strong signal of CT wasobserved in the FNAL E665 experiment on exclusive $\rho^{0}$- meson productionin deep inelastic scattering in the same range of $Q^{2}$. \\ We discuss theimpact of these observations on the CEBAF experimental program. We argue theyboth are good news, both were anticipated theoretically, and both rule in thecorrect QCD mechanism of the onset of CT.
