Cyclic grey

Summary

Cyclic grey is a cyclic colormap from colorcet. Lightness spans 0.30–0.84, hue sweeps 18°, and order breaks under protan, deutan, and tritan simulation.

Perceptual profile (OKLCh)

• Lightness: 0.571 → 0.567 (range 0.542, min 0.297, max 0.839); non-monotonic; midpoint 0.570
• Chroma: min 0.000, max 0.000, mean 0.000
• Hue: 178.4° → 178.4° (span 17.7°), path static
• Endpoint temperature: null → null
• Perceptual ΔE: total 103.5, mean/step 0.406, max step 0.540, smoothness 0.721, speed 0.406

Colorblind safety (ΔE under simulated CVD)

• Protanopia: ΔE total 103.5; preserves order: no
• Deuteranopia: ΔE total 103.5; preserves order: no
• Tritanopia: ΔE total 103.5; preserves order: no
