Black-Body Radiation

Summary

Black-Body Radiation is a sequential colormap from paraview. Lightness rises monotonically from 0.00 to 1.00, hue sweeps 110° from red to chartreuse, and order holds under all three colorblind…

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
