It is well known that galaxy properties correlate with the local environment in which galaxies reside, and this seems to hold at least up to z≈1. In contrast, it is still matter of debate why and when these environmental dependences originate, and whether the stellar mass is the only driver of these dependences, as galaxy properties depend on stellar mass, and stellar mass in turn depends on environment. In this context, I will present some results about the role played by stellar mass in the colour-density relation, as found in large and deep redshift surveys such as VVDS, zCOSMOS and DEEP2.
