## Summary

Kr 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 → 0.596 (range 0.596, min 0.000, max 0.596); monotonic; midpoint 0.368
- Chroma: min 0.000, max 0.223, mean 0.131
- Hue: 0.0° → 32.4° (span 49.9°), path monotonic-cw; quadrants: orange
- Endpoint temperature: null → warm
- Perceptual ΔE: total 60.8, mean/step 0.239, max step 0.651, smoothness 0.464, speed 0.239

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 39.3; preserves order: yes
- Deuteranopia: ΔE total 55.2; preserves order: yes
- Tritanopia: ΔE total 66.1; preserves order: yes
