Key Takeaways
- Chroma varies widely even within the same hue family — chemistry and crystal structure (e.g., PY 191 vs. PY 110) significantly affect strength, not just shade angle.
- Red is the broadest family, spanning nearly the full hue circle from yellow-red through to blue-red (pink/violet) shades — useful for formulators needing fine shade control.
- PVC-Tint performance data like this helps narrow down product selection quickly when a specific hue-chroma target needs to be matched without extensive lab trials.
