## Summary

Fire is a sequential colormap from the colorcet collection. Inspect its perceptual lightness, chroma, and hue profile on colorcurio.us.

Black→red→yellow→white; designed for dark canvases.

## Perceptual profile (OKLCh)

- Lightness: 0.000 → 1.000 (range 1.000, min 0.000, max 1.000); monotonic; midpoint 0.596
- Chroma: min 0.000, max 0.241, mean 0.167
- Hue: 0.0° → 0.0° (span 107.9°), path monotonic-cw; quadrants: red, orange, yellow, chartreuse
- Endpoint temperature: null → null
- Perceptual ΔE: total 163.6, mean/step 0.642, max step 7.279, smoothness 0.000, speed 0.642

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 123.0; preserves order: yes
- Deuteranopia: ΔE total 122.2; preserves order: yes
- Tritanopia: ΔE total 135.5; preserves order: yes
