relativistic yellow

LITGold looks yellow because it absorbs blue. Its 5d → 6s interband edge sits near 2.4 eV (about 520 nm), so blue and violet are absorbed and longer wavelengths reflect. Silver's edge is in the ultraviolet (about 3.9 eV), so it reflects everything and looks white. The difference is largely relativistic: gold's fast inner electrons contract the 6s orbital and lower it, closing the gap. Without relativity, calculations put gold's edge in the UV too (≈3.5 eV, used in batch 12).

MODELReflectance is a logistic step at each edge, and the colours come through CIE 1931 2° with Bradford to D65. The plates are nested: orange copper (edge ~2.1 eV), then a purple-filtered shadow, a green patina, gold yellow, the void.
