Zoom on the galaxy distribution within the VIPERS W1 field, where now the additional dimension of galaxy rest-frame colours has been added. Galaxies are here marked in blue, green or reddish, depending on whether their U − B rest-frame colour is respectively <0.9, between 0.9 and 1.2, or >1.2. Also in this case the size of the dots has been set proportionally to the B-band luminosity of the corresponding galaxy. The plot shows clearly that the colour–density relation for galaxies is already in place at these redshifts (Cucciati et al. 2006), with red early-type galaxies tracing the backbone of structure and blue/green star-forming objects filling the more peripheral lower-density regions. This picture gives an example of the potential of VIPERS for studying the clustering of galaxies as a function of galaxy properties, over scales ranging from less than a Mpc to well above 100 Mpc.
