## Summary

VikO is a cyclic colormap from the crameri collection. Inspect its perceptual lightness, chroma, and hue profile on colorcurio.us.

Cyclic variant of vik. Sourced from ScientificColourMaps8/vikO/vikO.txt.

## Perceptual profile (OKLCh)

- Lightness: 0.313 → 0.313 (range 0.509, min 0.313, max 0.822); non-monotonic; midpoint 0.819
- Chroma: min 0.002, max 0.123, mean 0.083
- Hue: 343.4° → 345.0° (span 171.5°), path monotonic-cw; quadrants: rose, magenta, violet, blue, azure, orange, red
- Endpoint temperature: warm → warm
- Perceptual ΔE: total 162.8, mean/step 0.639, max step 0.949, smoothness 0.846, speed 0.639
