HODs segregated by galaxy color and environment. Top row: HODs (left) and their corresponding ratios (right) for red central galaxies ((g − r) > 0.83). Bottom row: Equivalent analysis for blue centrals ((g − r)≤0.83). Each column represents a different magnitude cut (M_r < −19.76, −20.0, −20.5, and −21.0). Solid black lines show the complete sample (“all”), while colored symbols represent environmental subsamples (clusters, cluster outskirts, filaments, filament outskirts, and others). Ratio panels compare each environment’s HOD to the corresponding color-classified complete sample (all red or all blue).
