## Summary

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

## Perceptual profile (OKLCh)

- Lightness: 0.415 → 0.911 (range 0.495, min 0.415, max 0.911); monotonic; midpoint 0.654
- Chroma: min 0.001, max 0.222, mean 0.108
- Hue: 265.8° → 101.4° (span 195.6°), path folded; quadrants: blue, violet, chartreuse
- Endpoint temperature: cool → warm
- Perceptual ΔE: total 89.9, mean/step 0.352, max step 0.803, smoothness 0.618, speed 0.352

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 81.9; preserves order: yes
- Deuteranopia: ΔE total 86.6; preserves order: yes
- Tritanopia: ΔE total 65.4; preserves order: yes
