Cyclic BGRMB

Summary

Cyclic BGRMB is a cyclic colormap from colorcet. Lightness spans 0.49–0.74, hue sweeps 360° from violet to magenta, and order breaks under protan, deutan, and tritan simulation.

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
