## Summary

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

Linear-lightness modification of MATLAB hot palette.

## Perceptual profile (OKLCh)

- Lightness: 0.104 → 0.947 (range 0.842, min 0.104, max 0.947); monotonic; midpoint 0.576
- Chroma: min 0.009, max 0.230, mean 0.158
- Hue: 18.6° → 107.9° (span 94.6°), path folded; quadrants: red, orange, yellow, chartreuse
- Endpoint temperature: warm → warm
- Perceptual ΔE: total 144.3, mean/step 0.566, max step 1.417, smoothness 0.553, speed 0.566

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 100.2; preserves order: yes
- Deuteranopia: ΔE total 95.3; preserves order: yes
- Tritanopia: ΔE total 127.2; preserves order: no
