## Summary

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

## Perceptual profile (OKLCh)

- Lightness: 0.712 → 0.708 (range 0.469, min 0.453, max 0.922); non-monotonic; midpoint 0.659
- Chroma: min 0.062, max 0.279, mean 0.193
- Hue: 327.1° → 326.4° (span 359.2°), path monotonic-cw; quadrants: magenta, rose, red, orange, yellow, chartreuse, green, mint, cyan, azure, blue, violet
- Endpoint temperature: cool → cool
- Perceptual ΔE: total 218.7, mean/step 0.858, max step 2.594, smoothness 0.389, speed 0.858

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 178.2; preserves order: no
- Deuteranopia: ΔE total 186.4; preserves order: no
- Tritanopia: ΔE total 169.7; preserves order: no
