CB-tritan cyclic
Summary
CB-tritan cyclic is a cyclic colormap from colorcet. Lightness spans 0.50–0.98, hue sweeps 174° from azure to red, and order breaks under protan, deutan, and tritan simulation.
Perceptual profile (OKLCh)
- Lightness: 0.732 → 0.729 (range 0.476, min 0.503, max 0.979); non-monotonic; midpoint 0.754
- Chroma: min 0.001, max 0.122, mean 0.061
- Hue: 213.9° → 213.9° (span 174.4°), path monotonic-ccw; quadrants: azure, red
- Endpoint temperature: cool → cool
- Perceptual ΔE: total 139.0, mean/step 0.545, max step 0.969, smoothness 0.738, speed 0.545
Colorblind safety (ΔE under simulated CVD)
- Protanopia: ΔE total 103.1; preserves order: no
- Deuteranopia: ΔE total 114.4; preserves order: no
- Tritanopia: ΔE total 155.5; preserves order: no
