## Editorial Policy

All colorimetric data, Light Reflectance Values (LRV), and undertone profiles on Paint Undertones Guide are verified against spectrophotometric measurements and reviewed by Elena Vance, Lead Architectural Color Strategist (IACC-NA accredited). Computational models assist with data formatting, metamerism simulations, and responsive rendering under human expert supervision with a zero-hallucination guarantee. Physical paint sampling is always recommended before final paint specification.
