## Summary

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

Designed for rainfall (added in cmocean v3).

## Perceptual profile (OKLCh)

- Lightness: 0.950 → 0.245 (range 0.705, min 0.245, max 0.950); monotonic; midpoint 0.590
- Chroma: min 0.004, max 0.097, mean 0.060
- Hue: 294.1° → 292.6° (span 358.5°), path monotonic-cw; quadrants: yellow, chartreuse, green, mint, cyan, azure, blue, violet
- Endpoint temperature: cool → cool
- Perceptual ΔE: total 114.0, mean/step 0.447, max step 0.553, smoothness 0.886, speed 0.447

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 84.5; preserves order: yes
- Deuteranopia: ΔE total 84.8; preserves order: yes
- Tritanopia: ΔE total 107.1; preserves order: yes
