## Summary

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

High-contrast scientific ramp.

## Perceptual profile (OKLCh)

- Lightness: 0.278 → 0.434 (range 0.659, min 0.278, max 0.937); non-monotonic; midpoint 0.937
- Chroma: min 0.048, max 0.167, mean 0.125
- Hue: 268.5° → 24.4° (span 246.4°), path folded; quadrants: blue, violet, azure, cyan, mint, green, chartreuse, yellow, orange, red
- Endpoint temperature: cool → warm
- Perceptual ΔE: total 176.2, mean/step 0.691, max step 1.448, smoothness 0.699, speed 0.691
