Eclipse

Summary

Eclipse is a sequential colormap from cmasher. Lightness rises monotonically from 0.00 to 0.94, hue sweeps 280° from violet to yellow, and order holds under all three colorblind simulations.

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
