## Summary

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

Cyclic variant of cork. Sourced from ScientificColourMaps8/corkO/corkO.txt.

## Perceptual profile (OKLCh)

- Lightness: 0.364 → 0.364 (range 0.456, min 0.362, max 0.817); non-monotonic; midpoint 0.816
- Chroma: min 0.002, max 0.097, mean 0.055
- Hue: 97.1° → 101.1° (span 355.9°), path monotonic-ccw; quadrants: violet, blue, azure, cyan, mint, green, chartreuse
- Endpoint temperature: neutral → neutral
- Perceptual ΔE: total 138.7, mean/step 0.544, max step 0.765, smoothness 0.846, speed 0.544
