Emerald

Summary

Emerald is a sequential colormap from cmasher. Lightness rises monotonically from 0.00 to 0.90, hue sweeps 189° from green to cyan, and order holds under all three colorblind simulations.

Black→emerald sequential.

Perceptual profile (OKLCh)

• Lightness: 0.000 → 0.901 (range 0.901, min 0.000, max 0.901); monotonic; midpoint 0.502
• Chroma: min 0.000, max 0.152, mean 0.095
• Hue: 0.0° → 188.9° (span 188.9°), path monotonic-cw; quadrants: green, mint, cyan
• Endpoint temperature: null → cool
• Perceptual ΔE: total 89.1, mean/step 0.349, max step 0.578, smoothness 0.795, speed 0.349
