Ice & fire

Summary

Ice & fire is a diverging colormap from seaborn. Two arms meet at a pivot of lightness 0.24, hue sweeps 247° from mint to yellow, and order holds under all three colorblind simulations.

Cyan↔orange diverging on dark midpoint.

Perceptual profile (OKLCh)

• Lightness: 0.894 → 0.890 (range 0.657, min 0.237, max 0.894); non-monotonic; midpoint 0.237
• Chroma: min 0.001, max 0.177, mean 0.098
• Hue: 176.1° → 63.5° (span 247.4°), path monotonic-cw; quadrants: mint, cyan, azure, blue, violet, red, orange, yellow
• Pivot: t 0.498, lightness 0.237, hue jump 76.5°, smoothness 0.649
• Endpoint temperature: neutral → warm
• Perceptual ΔE: total 190.3, mean/step 0.746, max step 0.963, smoothness 0.873, speed 0.746
