## Summary

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

## Perceptual profile (OKLCh)

- Lightness: 1.000 → 0.551 (range 0.449, min 0.551, max 1.000); monotonic; midpoint 0.774
- Chroma: min 0.000, max 0.219, mean 0.118
- Hue: 197.2° → 30.4° (span 193.3°), path monotonic-cw; quadrants: azure, blue, violet, magenta, rose, red, orange
- Endpoint temperature: null → warm
- Perceptual ΔE: total 95.5, mean/step 0.374, max step 0.558, smoothness 0.776, speed 0.374

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 88.9; preserves order: yes
- Deuteranopia: ΔE total 81.1; preserves order: yes
- Tritanopia: ΔE total 100.3; preserves order: yes
