All the given compounds are colored due to charge transfer transitions. In KMnO₄ and K₂Cr₂O₇, it's ligand-to-metal charge transfer (LMCT). In $\left[\mathrm{Fe}{\left({\mathrm{H}}_2\mathrm{O}\right)}_5\mathrm{NO}\right]{\mathrm{SO}}_4$ (brown ring complex) and ${\mathrm{Na}}_2\left[\mathrm{Fe}(\mathrm{CN}{)}_5(\mathrm{NO})\right]$ (sodium nitroprusside), it involves metal-to-ligand charge transfer (MLCT) or intervalence charge transfer.
