## Summary

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

## Perceptual profile (OKLCh)

- Lightness: 0.277 → 0.940 (range 0.663, min 0.277, max 0.940); monotonic; midpoint 0.621
- Chroma: min 0.161, max 0.241, mean 0.200
- Hue: 264.2° → 105.2° (span 201.0°), path monotonic-cw; quadrants: blue, violet, magenta, rose, red, orange, yellow, chartreuse
- Endpoint temperature: cool → warm
- Perceptual ΔE: total 127.4, mean/step 0.500, max step 0.857, smoothness 0.636, speed 0.500

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 98.3; preserves order: no
- Deuteranopia: ΔE total 100.5; preserves order: yes
- Tritanopia: ΔE total 121.8; preserves order: no
