## Summary

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

## Perceptual profile (OKLCh)

- Lightness: 0.626 → 0.621 (range 0.634, min 0.303, max 0.938); non-monotonic; midpoint 0.622
- Chroma: min 0.001, max 0.167, mean 0.079
- Hue: 257.1° → 256.9° (span 200.1°), path monotonic-ccw; quadrants: blue, violet, yellow, chartreuse
- Endpoint temperature: cool → cool
- Perceptual ΔE: total 173.3, mean/step 0.680, max step 1.126, smoothness 0.825, speed 0.680

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 172.7; preserves order: no
- Deuteranopia: ΔE total 173.0; preserves order: no
- Tritanopia: ΔE total 157.7; preserves order: no
