## Summary

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

Cyclic variant of broc. Sourced from ScientificColourMaps8/brocO/brocO.txt.

## Perceptual profile (OKLCh)

- Lightness: 0.317 → 0.317 (range 0.544, min 0.317, max 0.861); non-monotonic; midpoint 0.861
- Chroma: min 0.010, max 0.074, mean 0.047
- Hue: 322.3° → 326.8° (span 355.5°), path monotonic-ccw; quadrants: magenta, violet, blue, azure, green, chartreuse, yellow
- Endpoint temperature: neutral → neutral
- Perceptual ΔE: total 148.7, mean/step 0.583, max step 0.740, smoothness 0.869, speed 0.583
