## Summary

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

## Perceptual profile (OKLCh)

- Lightness: 0.658 → 0.654 (range 0.291, min 0.654, max 0.946); non-monotonic; midpoint 0.946
- Chroma: min 0.001, max 0.183, mean 0.082
- Hue: 256.3° → 97.0° (span 200.7°), path monotonic-cw; quadrants: blue, violet, yellow, chartreuse
- Endpoint temperature: cool → warm
- Perceptual ΔE: total 80.1, mean/step 0.314, max step 0.559, smoothness 0.783, speed 0.314

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 78.0; preserves order: yes
- Deuteranopia: ΔE total 80.7; preserves order: yes
- Tritanopia: ΔE total 69.0; preserves order: yes
