Why is [Cu(H₂O)₆]²⁺ blue? And why does [Ni(NH₃)₆]²⁺ look completely different from [Ni(H₂O)₆]²⁺? The answer lies in Crystal Field Theory (CFT) — a beautiful, quantitative model that explains how ligands split the d‑orbitals of transition metals, and how electrons jumping between those split levels absorb specific colours of light.
