Dimgray

Summary

Dimgray is a sequential colormap from colorcet. Lightness rises monotonically from 0.22 to 0.96, hue sweeps 27°, and order holds under all three colorblind simulations.

Perceptual profile (OKLCh)

• Lightness: 0.224 → 0.957 (range 0.733, min 0.224, max 0.957); monotonic; midpoint 0.589
• Chroma: min 0.000, max 0.000, mean 0.000
• Hue: 197.2° → 179.0° (span 26.5°), path static
• Endpoint temperature: null → null
• Perceptual ΔE: total 66.2, mean/step 0.260, max step 0.335, smoothness 0.851, speed 0.260

Colorblind safety (ΔE under simulated CVD)

• Protanopia: ΔE total 66.2; preserves order: yes
• Deuteranopia: ΔE total 66.2; preserves order: yes
• Tritanopia: ΔE total 66.2; preserves order: yes
