## Summary

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

## Perceptual profile (OKLCh)

- Lightness: 0.193 → 0.948 (range 0.754, min 0.193, max 0.948); monotonic; midpoint 0.579
- Chroma: min 0.075, max 0.281, mean 0.191
- Hue: 264.1° → 186.4° (span 81.9°), path folded; quadrants: blue, azure, cyan
- Endpoint temperature: cool → cool
- Perceptual ΔE: total 102.1, mean/step 0.400, max step 0.514, smoothness 0.808, speed 0.400

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 90.2; preserves order: yes
- Deuteranopia: ΔE total 86.7; preserves order: yes
