## Summary

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

matplotlib default sequential variant.

## Perceptual profile (OKLCh)

- Lightness: 0.292 → 0.943 (range 0.651, min 0.292, max 0.943); monotonic; midpoint 0.592
- Chroma: min 0.152, max 0.221, mean 0.184
- Hue: 267.4° → 112.4° (span 205.0°), path monotonic-cw; quadrants: blue, violet, magenta, rose, red, orange, yellow, chartreuse
- Endpoint temperature: cool → warm
- Perceptual ΔE: total 121.9, mean/step 0.478, max step 0.655, smoothness 0.673, speed 0.478

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 97.1; preserves order: yes
- Deuteranopia: ΔE total 98.6; preserves order: yes
- Tritanopia: ΔE total 109.8; preserves order: yes
