Suprime-Cam aperture-color versus Kron-like magnitude diagram B − R_C versus R_C for the 421 spectroscopic cluster members with photometric information. The black solid line is the CMR, (B − R_C)_diff = 0. The blue dashed line shows the value (B − R_C)_diff = −0.5, which we used to separate green and blue galaxies (highlighted by green triangles and blue circles). The two red dashed lines show the locus of the red sequence galaxies, |(B − R_C)_diff|≤0.3, with the galaxies of the RedU and RedD samples marked with red circles and squares. A large black circle highlights the BCG.
