## Summary

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

## 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
