Cyclic WRWBW

Summary

Cyclic WRWBW is a cyclic colormap from colorcet. Lightness spans 0.54–0.88, hue sweeps 135° from red to blue, and order breaks under protan, deutan, and tritan simulation.

Perceptual profile (OKLCh)

• Lightness: 0.882 → 0.882 (range 0.343, min 0.539, max 0.882); non-monotonic; midpoint 0.873
• Chroma: min 0.011, max 0.209, mean 0.112
• Hue: 354.4° → 340.0° (span 134.9°), path folded; quadrants: red, orange, violet, blue
• Endpoint temperature: warm → warm
• Perceptual ΔE: total 195.7, mean/step 0.767, max step 1.067, smoothness 0.745, speed 0.767

Colorblind safety (ΔE under simulated CVD)

• Protanopia: ΔE total 185.6; preserves order: no
• Deuteranopia: ΔE total 184.5; preserves order: no
• Tritanopia: ΔE total 190.3; preserves order: no
