  In this work, we study the evolution with redshift of the colour-magnitude
relation (CMR) of early-type galaxies. This evolution is analyzed through
cosmological numerical simulations from z = 2 to z = 0. The preliminary results
shown here represent the starting point of a study aimed at identifying the
processes that originated the observed CMR of early-type galaxies at z = 0.
