## Summary

Gwv is a diverging colormap from the colorcet collection. Inspect its perceptual lightness, chroma, and hue profile on colorcurio.us.

## Perceptual profile (OKLCh)

- Lightness: 0.596 → 0.638 (range 0.344, min 0.596, max 0.940); non-monotonic; midpoint 0.940
- Chroma: min 0.001, max 0.212, mean 0.102
- Hue: 139.0° → 313.3° (span 185.7°), path monotonic-ccw; quadrants: green, magenta
- Endpoint temperature: warm → cool
- Perceptual ΔE: total 97.2, mean/step 0.381, max step 0.840, smoothness 0.685, speed 0.381

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 85.8; preserves order: yes
- Deuteranopia: ΔE total 80.9; preserves order: yes
- Tritanopia: ΔE total 78.4; preserves order: yes
