We investigated the typical environment and physical properties of "reddiscs" and "blue bulges", comparing those to the "normal" objects in the bluecloud and red sequence. Our sample is composed of cluster members and fieldgalaxies at $z \le 0.1$, so that we can assess the impact of the local andglobal environment. We find that disc galaxies display a strong dependence onenvironment, becoming redder for higher densities. This effect is morepronounced for objects within the virial radius, being also strong related tothe stellar mass. We find that local and global environment affect galaxyproperties, but the most effective parameter is stellar mass. We find evidencefor a scenario where "blue discs" are transformed into "red discs" as they growin mass and move to the inner parts of clusters. From the metallicitydifferences of red and blue discs, and the analysis of their star formationhistories, we suggest the quenching process is slow. We estimate a quenchingtime scale of $\sim $ 2$-$3 Gyr. We also find from the sSFR$-$M$_*$ plane that"red discs" gradually change as they move into clusters. The "blue bulges" havemany similar properties than "blue discs", but some of the former show strongsigns of asymmetry. The high asymmetry "blue bulges" display enhanced recentstar formation compared to their regular counterparts. That indicates some ofthese systems may have increased their star formation due to mergers.Nonetheless, there may not be a single evolutionary path for these blueearly-type objects.
