Black-body

Summary

Black-body is a sequential colormap from moreland. Lightness rises monotonically from 0.00 to 1.00, hue sweeps 110° from orange to chartreuse, and order holds under all three colorblind simulations.

Lightness-uniform black→red→yellow→white.

Perceptual profile (OKLCh)

• Lightness: 0.000 → 1.000 (range 1.000, min 0.000, max 1.000); monotonic; midpoint 0.586
• Chroma: min 0.000, max 0.181, mean 0.130
• Hue: 0.0° → 0.0° (span 109.5°), path folded; quadrants: orange, red, yellow, chartreuse
• Endpoint temperature: null → null
• Perceptual ΔE: total 153.7, mean/step 0.603, max step 2.666, smoothness 0.429, speed 0.603

Colorblind safety (ΔE under simulated CVD)

• Protanopia: ΔE total 118.3; preserves order: yes
• Deuteranopia: ΔE total 114.9; preserves order: yes
• Tritanopia: ΔE total 123.8; preserves order: yes
