## Summary

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

Black→orange→white astronomical.

## Perceptual profile (OKLCh)

- Lightness: 0.000 → 0.944 (range 0.944, min 0.000, max 0.944); monotonic; midpoint 0.525
- Chroma: min 0.000, max 0.172, mean 0.066
- Hue: 0.0° → 105.2° (span 279.6°), path monotonic-ccw; quadrants: violet, blue, azure, cyan, mint, green, chartreuse, yellow
- Endpoint temperature: null → warm
- Perceptual ΔE: total 114.1, mean/step 0.447, max step 0.575, smoothness 0.801, speed 0.447

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 96.9; preserves order: yes
- Deuteranopia: ΔE total 99.4; preserves order: yes
- Tritanopia: ΔE total 110.9; preserves order: yes
