## Summary

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

Isoluminant full-hue-circle cycle; for azimuth/phase data.

## Perceptual profile (OKLCh)

- Lightness: 0.726 → 0.704 (range 0.102, min 0.675, max 0.777); non-monotonic; midpoint 0.762
- Chroma: min 0.130, max 0.290, mean 0.198
- Hue: 328.1° → 339.6° (span 348.5°), path monotonic-ccw; quadrants: magenta, violet, blue, azure, cyan, mint, green, chartreuse, yellow, orange, red, rose
- Endpoint temperature: cool → warm
- Perceptual ΔE: total 210.9, mean/step 0.827, max step 1.737, smoothness 0.462, speed 0.827

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 147.1; preserves order: no
- Deuteranopia: ΔE total 121.4; preserves order: no
- Tritanopia: ΔE total 169.7; preserves order: no
