## Summary

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

Designed for bathymetry / depth.

## Perceptual profile (OKLCh)

- Lightness: 0.983 → 0.244 (range 0.739, min 0.244, max 0.983); monotonic; midpoint 0.610
- Chroma: min 0.038, max 0.104, mean 0.083
- Hue: 107.9° → 318.0° (span 210.1°), path monotonic-cw; quadrants: chartreuse, green, mint, cyan, azure, blue, violet, magenta
- Endpoint temperature: warm → neutral
- Perceptual ΔE: total 106.2, mean/step 0.416, max step 0.511, smoothness 0.882, speed 0.416

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 89.6; preserves order: yes
- Deuteranopia: ΔE total 90.1; preserves order: yes
- Tritanopia: ΔE total 103.3; preserves order: yes
