## Summary

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

256-class auto-distinct categorical, both-bg-safe.

## Perceptual profile (OKLCh)

- Lightness: 0.552 → 0.422 (range 0.763, min 0.216, max 0.979); non-monotonic; midpoint 0.475
- Chroma: min 0.036, max 0.300, mean 0.131
- Hue: 29.2° → 270.9° (span 360.0°), path folded; quadrants: red, violet, green, azure, rose, yellow, cyan, blue, mint, orange, magenta, chartreuse
