## Summary

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

Astronomy-flavored hot variant.

## Perceptual profile (OKLCh)

- Lightness: 0.000 → 1.000 (range 1.000, min 0.000, max 1.000); monotonic; midpoint 0.626
- Chroma: min 0.000, max 0.258, mean 0.158
- Hue: 0.0° → 0.0° (span 67.8°), path monotonic-cw; quadrants: red, orange, yellow
- Endpoint temperature: null → null
- Perceptual ΔE: total 133.9, mean/step 0.525, max step 1.287, smoothness 0.553, speed 0.525

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 103.8; preserves order: yes
- Deuteranopia: ΔE total 107.7; preserves order: yes
- Tritanopia: ΔE total 133.0; preserves order: yes
