The color of gold differs from other metals due to relativistic effects on its electron configuration. Specifically, the transition to the p-orbital in gold occurs at a lower energy level compared to silver, shifting the absorption spectrum into the blue range. This results in gold reflecting yellow light, which is the complementary color to blue, giving it its characteristic golden hue. The large atomic size of gold contributes to the rapid movement of its electrons, enhancing these relativistic corrections.
