## Summary

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

## Perceptual profile (OKLCh)

- Lightness: 0.177 → 0.967 (range 0.790, min 0.177, max 0.967); monotonic; midpoint 0.610
- Chroma: min 0.000, max 0.249, mean 0.175
- Hue: 182.0° → 109.6° (span 155.4°), path folded; quadrants: red, orange, yellow, chartreuse
- Endpoint temperature: null → warm
- Perceptual ΔE: total 126.0, mean/step 0.494, max step 2.064, smoothness 0.509, speed 0.494

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 85.8; preserves order: yes
- Deuteranopia: ΔE total 86.5; preserves order: yes
- Tritanopia: ΔE total 127.1; preserves order: yes
