## Summary

Kbgyw 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 → 0.983 (range 0.806, min 0.177, max 0.983); monotonic; midpoint 0.568
- Chroma: min 0.000, max 0.214, mean 0.153
- Hue: 182.0° → 179.0° (span 207.4°), path folded; quadrants: magenta, violet, blue, azure, cyan, mint, green, chartreuse
- Endpoint temperature: null → null
- Perceptual ΔE: total 187.2, mean/step 0.734, max step 7.142, smoothness 0.052, speed 0.734
