## Summary

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

## Perceptual profile (OKLCh)

- Lightness: 0.172 → 0.939 (range 0.767, min 0.172, max 0.939); monotonic; midpoint 0.551
- Chroma: min 0.045, max 0.264, mean 0.172
- Hue: 151.1° → 120.3° (span 30.7°), path monotonic-ccw; quadrants: mint, green
- Endpoint temperature: neutral → warm
- Perceptual ΔE: total 88.9, mean/step 0.348, max step 0.690, smoothness 0.759, speed 0.348

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 79.4; preserves order: yes
- Deuteranopia: ΔE total 79.0; preserves order: yes
- Tritanopia: ΔE total 92.4; preserves order: yes
