## Summary

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

## Perceptual profile (OKLCh)

- Lightness: 0.491 → 0.492 (range 0.249, min 0.491, max 0.740); non-monotonic; midpoint 0.492
- Chroma: min 0.036, max 0.273, mean 0.192
- Hue: 275.6° → 275.8° (span 360.0°), path monotonic-ccw; quadrants: violet, blue, azure, cyan, mint, green, chartreuse, yellow, orange, red, rose, magenta
- Endpoint temperature: cool → cool
- Perceptual ΔE: total 228.9, mean/step 0.898, max step 3.077, smoothness 0.444, speed 0.898

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 185.9; preserves order: no
- Deuteranopia: ΔE total 176.7; preserves order: no
- Tritanopia: ΔE total 203.2; preserves order: no
