## Summary

2hot is a sequential colormap from the paraview collection. Inspect its perceptual lightness, chroma, and hue profile on colorcurio.us.

Doubled hot ramp; black→red→yellow→white→blue.

## Perceptual profile (OKLCh)

- Lightness: 0.093 → 1.000 (range 0.907, min 0.093, max 1.000); monotonic; midpoint 0.680
- Chroma: min 0.000, max 0.244, mean 0.166
- Hue: 29.2° → 0.0° (span 109.4°), path monotonic-ccw; quadrants: red, orange, yellow, chartreuse
- Endpoint temperature: warm → null
- Perceptual ΔE: total 161.4, mean/step 0.633, max step 2.041, smoothness 0.510, speed 0.633
