## Summary

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

matplotlib default sequential variant; very dark start.

## Perceptual profile (OKLCh)

- Lightness: 0.053 → 0.978 (range 0.924, min 0.053, max 0.978); monotonic; midpoint 0.541
- Chroma: min 0.028, max 0.184, mean 0.136
- Hue: 280.2° → 108.6° (span 188.5°), path monotonic-cw; quadrants: violet, magenta, rose, red, orange, yellow, chartreuse
- Endpoint temperature: cool → warm
- Perceptual ΔE: total 138.6, mean/step 0.544, max step 0.985, smoothness 0.739, speed 0.544

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 116.1; preserves order: yes
- Deuteranopia: ΔE total 117.3; preserves order: yes
- Tritanopia: ΔE total 124.6; preserves order: yes
