## Summary

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

Designed for wave amplitude / positive-only fields.

## Perceptual profile (OKLCh)

- Lightness: 0.949 → 0.239 (range 0.710, min 0.239, max 0.949); monotonic; midpoint 0.587
- Chroma: min 0.005, max 0.168, mean 0.104
- Hue: 30.3° → 16.1° (span 26.2°), path monotonic-ccw; quadrants: orange, red
- Endpoint temperature: null → warm
- Perceptual ΔE: total 85.2, mean/step 0.334, max step 0.376, smoothness 0.906, speed 0.334

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 79.8; preserves order: yes
- Deuteranopia: ΔE total 75.9; preserves order: yes
- Tritanopia: ΔE total 84.5; preserves order: yes
