## Summary

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

Plotly electric arc ramp; black→purple→amber.

## Perceptual profile (OKLCh)

- Lightness: 0.000 → 0.981 (range 0.981, min 0.000, max 0.981); monotonic; midpoint 0.439
- Chroma: min 0.000, max 0.172, mean 0.130
- Hue: 0.0° → 99.3° (span 179.3°), path monotonic-cw; quadrants: magenta, violet, rose, red, orange, yellow, chartreuse
