## Summary

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

## Perceptual profile (OKLCh)

- Lightness: 0.215 → 0.961 (range 0.745, min 0.215, max 0.961); monotonic; midpoint 0.605
- Chroma: min 0.033, max 0.301, mean 0.225
- Hue: 264.2° → 325.9° (span 63.4°), path monotonic-cw; quadrants: blue, violet, magenta
- Endpoint temperature: cool → neutral
- Perceptual ΔE: total 94.2, mean/step 0.369, max step 0.800, smoothness 0.716, speed 0.369

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 80.8; preserves order: yes
- Deuteranopia: ΔE total 85.7; preserves order: yes
