## Summary

Black-Body Radiation is a sequential colormap from the paraview collection. Inspect its perceptual lightness, chroma, and hue profile on colorcurio.us.

Classic 4-anchor black→red→yellow→white thermal.

## Perceptual profile (OKLCh)

- Lightness: 0.000 → 1.000 (range 1.000, min 0.000, max 1.000); monotonic; midpoint 0.606
- Chroma: min 0.000, max 0.238, mean 0.156
- Hue: 0.0° → 0.0° (span 109.8°), path monotonic-cw; quadrants: red, orange, yellow, chartreuse
- Endpoint temperature: null → null
- Perceptual ΔE: total 161.2, mean/step 0.632, max step 2.328, smoothness 0.486, speed 0.632

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 118.8; preserves order: yes
- Deuteranopia: ΔE total 117.7; preserves order: yes
- Tritanopia: ΔE total 133.7; preserves order: yes
