Batlow W

Summary

Batlow W is a sequential colormap from crameri. Lightness rises monotonically from 0.25 to 1.00, hue sweeps 245° from blue to red, and order holds under all three colorblind simulations.

White-anchored batlow variant; light-mode sequential.

Perceptual profile (OKLCh)

• Lightness: 0.251 → 0.998 (range 0.747, min 0.251, max 0.998); monotonic; midpoint 0.597
• Chroma: min 0.001, max 0.119, mean 0.078
• Hue: 262.9° → 19.9° (span 244.5°), path monotonic-ccw; quadrants: blue, azure, cyan, mint, green, chartreuse, yellow, orange, red
• Endpoint temperature: cool → null
• Perceptual ΔE: total 138.6, mean/step 0.544, max step 0.556, smoothness 0.994, speed 0.544
