## Summary

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

Lab linear-lightness yellow-green-blue ramp.

## Perceptual profile (OKLCh)

- Lightness: 0.992 → 0.368 (range 0.649, min 0.343, max 0.992); non-monotonic; midpoint 0.618
- Chroma: min 0.007, max 0.164, mean 0.107
- Hue: 80.7° → 292.5° (span 213.0°), path monotonic-cw; quadrants: yellow, chartreuse, green, mint, cyan, azure, blue, violet
- Endpoint temperature: warm → cool
- Perceptual ΔE: total 128.7, mean/step 0.505, max step 1.366, smoothness 0.626, speed 0.505
