Distribution of the stellar masses as a function of the rest-frame (U − V) colors in the redshift range 0.8 ≤ z ≤ 1.2. The red dashed line represents the red sequence cut defined by Borch et al. (2006), while the green short dashed line defines an approximate green valley region, both lines are calculated at redshift  ~1. The points are color coded as in Fig. 12.
