## Summary

Fes is a multi-sequential colormap from the crameri collection. Inspect its perceptual lightness, chroma, and hue profile on colorcurio.us.

Multi-sequential bathymetry+topography. Sourced from ScientificColourMaps8/fes/fes.txt.

## Perceptual profile (OKLCh)

- Lightness: 0.158 → 0.950 (range 0.800, min 0.158, max 0.958); non-monotonic; midpoint 0.958
- Chroma: min 0.000, max 0.098, mean 0.033
- Hue: 0.0° → 286.5° (span 360.0°), path folded; quadrants: mint, green, chartreuse, yellow, violet
- Endpoint temperature: null → cool
- Perceptual ΔE: total 228.9, mean/step 0.898, max step 67.351, smoothness 0.000, speed 0.898

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 207.4; preserves order: no
- Deuteranopia: ΔE total 214.2; preserves order: no
- Tritanopia: ΔE total 233.3; preserves order: no
