Polyhalides are colored due to the presence of partially filled d-orbitals in the metal ions or due to charge transfer transitions between the halide ligands and the central metal ion. When light interacts with these complexes, specific wavelengths are absorbed, leading to the emission of complementary colors. Additionally, the geometry and electronic environment of the polyhalide can influence the energy levels of the d-orbitals, further affecting their color properties.
