  Color fluctuations in hadron-hadron collisions are responsible for the
presence of inelastic diffraction and lead to distinctive differences between
the Gribov picture of high energy scattering and the low energy Glauber
picture. We find that color fluctuations give a larger contribution to the
fluctuations of the number of wounded nucleons than the fluctuations of the
number of nucleons at a given impact parameter. The two contributions for the
impact parameter averaged fluctuations are comparable. As a result, standard
procedures for selecting peripheral (central) collisions lead to selection of
configurations in the projectile which interact with smaller (larger) than
average strength. We suggest that studies of pA collisions with a hard trigger
may allow to observe effects of color fluctuations.
