## Summary

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

Yorick legacy DEM ramp.

## Perceptual profile (OKLCh)

- Lightness: 0.000 → 0.985 (range 0.985, min 0.000, max 0.985); monotonic; midpoint 0.701
- Chroma: min 0.000, max 0.154, mean 0.111
- Hue: 0.0° → 0.0° (span 360.0°), path folded; quadrants: blue, azure, cyan, mint, green, chartreuse, yellow
- Endpoint temperature: null → null
- Perceptual ΔE: total 185.0, mean/step 0.725, max step 5.517, smoothness 0.037, speed 0.725
