## Summary

Kb 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 → 0.535 (range 0.535, min 0.000, max 0.535); monotonic; midpoint 0.337
- Chroma: min 0.000, max 0.258, mean 0.149
- Hue: 0.0° → 264.2° (span 101.7°), path monotonic-ccw; quadrants: blue
- Endpoint temperature: null → cool
- Perceptual ΔE: total 52.9, mean/step 0.207, max step 0.754, smoothness 0.355, speed 0.207

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 55.6; preserves order: yes
- Deuteranopia: ΔE total 52.7; preserves order: yes
- Tritanopia: ΔE total 47.4; preserves order: yes
