Red-to-blue galaxy ratio (N_red/N_blue) as a function of halo mass (log₁₀(M_halo/[M_⊙h⁻¹]) for different galactic environments (color-coded) and four magnitude cuts (panels). The ratio increases systematically with halo mass in all environments, with the steepest growth occurring in the densest regions (clusters > cluster outskirts > filaments > filament outskirts > field). This mass- and density-dependent trend persists consistently across all magnitude cuts. Error bars show propagated uncertainties from jackknife-estimated HOD errors.
