## Summary

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

Perceptually uniform grey ramp.

## Perceptual profile (OKLCh)

- Lightness: 0.005 → 0.999 (range 0.993, min 0.005, max 0.999); monotonic; midpoint 0.546
- Chroma: min 0.000, max 0.002, mean 0.001
- Hue: 265.1° → 100.4° (span 195.3°), path static
- Endpoint temperature: null → null
- Perceptual ΔE: total 75.1, mean/step 0.294, max step 0.379, smoothness 0.781, speed 0.294

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 75.1; preserves order: yes
- Deuteranopia: ΔE total 75.1; preserves order: yes
- Tritanopia: ΔE total 75.1; preserves order: yes
