  The 1993 witnessed two major news in the field of color transparency (CT): i)
no effect of CT was seen in the SLAC NE18 experiment on $A(e,e'p)$ scattering
at virtualities of the exchanged photon $Q^{2} \lsim 7$ GeV$^{2}$, ii) strong
signal of CT was observed in the Fermilab E665 experiment on exclusive
$\rho^{0}$-meson production in deep inelastic scattering in the same range of
$Q^{2}$. Both are good news and rule in CT, since this striking difference in
the onset of CT for two reactions was predicted theoretically, and we review
the theory of both reactions and the origin of this difference. We discuss an
importance of final state interaction effects for the theoretical
interpretation of the NE18 data. We comment on possible CT effects in the
$^{4}He(e,e'p)$ interactions at CEBAF.
