## Summary

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

## Perceptual profile (OKLCh)

- Lightness: 0.635 → 0.635 (range 0.267, min 0.603, max 0.871); non-monotonic; midpoint 0.846
- Chroma: min 0.092, max 0.230, mean 0.164
- Hue: 31.4° → 30.9° (span 359.5°), path monotonic-cw; quadrants: orange, yellow, chartreuse, green, mint, cyan, azure, blue, violet, magenta, rose, red
- Endpoint temperature: warm → warm
- Perceptual ΔE: total 253.6, mean/step 0.995, max step 1.365, smoothness 0.801, speed 0.995

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 207.7; preserves order: no
- Deuteranopia: ΔE total 200.5; preserves order: no
- Tritanopia: ΔE total 224.2; preserves order: no
