## Summary

Cyclic grey is a cyclic colormap from the colorcet collection. Inspect its perceptual lightness, chroma, and hue profile on colorcurio.us.

## 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
