Hue L60
Summary
Hue L60 is a cyclic colormap from paraview. Lightness spans 0.68–0.69, hue sweeps 360° from red to orange, and order breaks under protan, deutan, and tritan simulation.
Lab-based isoluminant hue cycle at L=60.
Perceptual profile (OKLCh)
- Lightness: 0.689 → 0.689 (range 0.012, min 0.682, max 0.694); non-monotonic; midpoint 0.684
- Chroma: min 0.094, max 0.187, mean 0.153
- Hue: 27.9° → 27.9° (span 360.0°), path monotonic-ccw; quadrants: red, rose, magenta, violet, blue, azure, cyan, mint, green, chartreuse, yellow, orange
- Endpoint temperature: warm → warm
- Perceptual ΔE: total 186.7, mean/step 0.732, max step 1.226, smoothness 0.652, speed 0.732
Colorblind safety (ΔE under simulated CVD)
- Protanopia: ΔE total 126.5; preserves order: no
- Deuteranopia: ΔE total 112.5; preserves order: no
- Tritanopia: ΔE total 148.5; preserves order: no
