The colour versus stellar mass distribution as a function of environment
The animated figure below shows how the galaxy colour-mass distribution varies with environment.
The contours are logarithmically spaced in number density with 4 contours per factor of 10.
The grey regions represent the mean color plus/minus 1-sigma of the red and blue sequences.
This is an animated version of Figure 9 of
Baldry et al. 2006.
