Saturation distribution observed in real professional wallpaper: S<20% = 34.1% of all color usage, S 20–40% = 30.0%, S>60% = 13.5%. Most professional wallpapers use a low-saturation, tone-on-tone or 2–3 color story. Median distinct hues per design = 3; 90th percentile = 4. Keep total distinct hues per design ≤ 5. Never use neon, fluorescent, rainbow, primary-saturated red/yellow/blue, hot pink, or electric green. Prefer aged, slightly-grayed, archival pigments over pure chromatic colors.
