We outline major ideas involved in discussion of color coherence phenomena
(CCP) at intermediate energies. We point out that the recent advances in ca
lculating cross sections of hard exclusive processes off light nuclei allow
to use the lightest nuclei for sensitive tests of CCP. Consistency of the
results of the measurements of color transparency in quasielastic A(p,2p) a
nd A(e,e'p) processes is emphasized. Evidence for presence of significant c
olor fluctuations in nucleons and pions emerging from the study of diffract
ive processes is summarized. A new class of hard processes leading to three
particle final state is suggested for electron and hadron projectiles.
