## Summary

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

Perceptually uniform grey ramp. Sourced from ScientificColourMaps8/grayC/grayC.txt.

## Perceptual profile (OKLCh)

- Lightness: 0.000 → 1.000 (range 1.000, min 0.000, max 1.000); monotonic; midpoint 0.568
- Chroma: min 0.000, max 0.000, mean 0.000
- Hue: 0.0° → 0.0° (span 194.9°), path static
- Endpoint temperature: null → null
- Perceptual ΔE: total 75.2, mean/step 0.295, max step 0.300, smoothness 0.992, speed 0.295

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 75.2; preserves order: yes
- Deuteranopia: ΔE total 75.2; preserves order: yes
- Tritanopia: ΔE total 75.2; preserves order: yes
