## Summary

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

## Perceptual profile (OKLCh)

- Lightness: 0.177 → 0.957 (range 0.780, min 0.177, max 0.957); monotonic; midpoint 0.567
- Chroma: min 0.000, max 0.175, mean 0.105
- Hue: 182.0° → 87.2° (span 94.8°), path monotonic-ccw; quadrants: chartreuse, yellow
- Endpoint temperature: null → warm
- Perceptual ΔE: total 107.7, mean/step 0.422, max step 3.151, smoothness 0.143, speed 0.422
