Color-magnitude and color-color diagrams for ringed galaxies in groups are displayed. Upper panels: color-magnitude diagrams for ringed galaxies in poor and rich groups (represented by blue and magenta contours, respectively), and their corresponding control samples (represented by gray contours). The vertical panels show the M_u − M_r normalized distributions for each sample. Top-most panels depict the normalized M_r distributions for the same galaxy samples. Lower panels: color-color diagrams for ringed galaxies in poor groups (blue outlines), in rich groups (magenta outlines) and galaxies in their respective control samples (gray surface outlines). The vertical panels show the M_g − M_r normalized distributions for each sample.
