Colour magnitude diagrams for the samples eSCGS, MLS_ur, and MLS_W1 (left to right). Different colours indicate morphological types (top) or the fracDeV type (bottom). Morphological peculiarities are indicated by an overplottet plus sign, a framed “M” (top raw) indicates a merger system. The dashed lines mark the approximate border of the colour selection area for the magnitude-limited samples (see text). The magenta contours show the population density of nearby galaxies from SDSS. The solid lines mark the transition between red sequence and green valley (red) and green valley and blue cloud (green).
