## Summary

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

Electric purple-blue sequential.

## Perceptual profile (OKLCh)

- Lightness: 0.000 → 1.000 (range 1.000, min 0.000, max 1.000); monotonic; midpoint 0.567
- Chroma: min 0.000, max 0.223, mean 0.118
- Hue: 0.0° → 0.0° (span 134.8°), path monotonic-cw; quadrants: rose, magenta, violet, blue, azure
- Endpoint temperature: null → null
- Perceptual ΔE: total 124.6, mean/step 0.489, max step 0.951, smoothness 0.766, speed 0.489
