## Summary

Kry (pure) is a sequential colormap from the colorcet collection. Inspect its perceptual lightness, chroma, and hue profile on colorcurio.us.

## Perceptual profile (OKLCh)

- Lightness: 0.000 → 0.968 (range 0.968, min 0.000, max 0.968); monotonic; midpoint 0.583
- Chroma: min 0.000, max 0.240, mean 0.170
- Hue: 0.0° → 109.8° (span 109.8°), path monotonic-cw; quadrants: red, orange, yellow, chartreuse
- Endpoint temperature: null → warm
- Perceptual ΔE: total 128.5, mean/step 0.504, max step 2.516, smoothness 0.443, speed 0.504

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 87.2; preserves order: yes
