## Summary

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

Black→magenta→cream, astronomy.

## Perceptual profile (OKLCh)

- Lightness: 0.000 → 0.899 (range 0.899, min 0.000, max 0.899); monotonic; midpoint 0.531
- Chroma: min 0.000, max 0.256, mean 0.142
- Hue: 0.0° → 170.8° (span 189.2°), path monotonic-ccw; quadrants: magenta, violet, blue, azure, cyan, mint
- Endpoint temperature: null → warm
- Perceptual ΔE: total 133.5, mean/step 0.523, max step 0.852, smoothness 0.776, speed 0.523
