## Summary

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

vispy preset 'hot' (blackbody-like K→W ramp).

## Perceptual profile (OKLCh)

- Lightness: 0.000 → 1.000 (range 1.000, min 0.000, max 1.000); monotonic; midpoint 0.796
- Chroma: min 0.000, max 0.258, mean 0.144
- Hue: 0.0° → 0.0° (span 109.8°), path monotonic-cw; quadrants: red, orange, yellow, chartreuse
- Endpoint temperature: null → null
- Perceptual ΔE: total 169.9, mean/step 0.666, max step 1.522, smoothness 0.618, speed 0.666

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 124.9; preserves order: yes
- Deuteranopia: ΔE total 124.8; preserves order: yes
- Tritanopia: ΔE total 138.4; preserves order: yes
