## Summary

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

CVD-optimized sequential; Nuñez, Anderton, Renslow 2018.

## Perceptual profile (OKLCh)

- Lightness: 0.260 → 0.921 (range 0.661, min 0.260, max 0.921); monotonic; midpoint 0.583
- Chroma: min 0.000, max 0.179, mean 0.072
- Hue: 256.1° → 101.7° (span 175.6°), path folded; quadrants: blue, violet, chartreuse
- Endpoint temperature: cool → warm
- Perceptual ΔE: total 87.3, mean/step 0.343, max step 0.450, smoothness 0.862, speed 0.343

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 86.0; preserves order: yes
- Deuteranopia: ΔE total 88.4; preserves order: yes
- Tritanopia: ΔE total 76.2; preserves order: yes
