Cyclic WRKBW

Summary

Cyclic WRKBW is a cyclic colormap from colorcet. Lightness spans 0.26–0.89, hue sweeps 134° from red to blue, and order holds under all three colorblind simulations.

Perceptual profile (OKLCh)

• Lightness: 0.888 → 0.888 (range 0.628, min 0.260, max 0.888); non-monotonic; midpoint 0.261
• Chroma: min 0.011, max 0.213, mean 0.113
• Hue: 354.4° → 340.0° (span 134.0°), path monotonic-ccw; quadrants: red, orange, violet, blue
• Endpoint temperature: warm → warm
• Perceptual ΔE: total 187.3, mean/step 0.735, max step 1.079, smoothness 0.825, speed 0.735

Colorblind safety (ΔE under simulated CVD)

• Protanopia: ΔE total 170.6; preserves order: yes
• Deuteranopia: ΔE total 179.8; preserves order: yes
• Tritanopia: ΔE total 190.1; preserves order: yes
