The colour exhibited by the transition metal ions is due to their ability to absorb light in the visible region of the electromagnetic spectrum. This causes unpaired d electrons to rise from a lower to a higher energy state. Ions which have the electronic configuration 3d(10), including the Scandium (III) Ion, Sc(+++) and the Copper (I) Ion, Cu(+), are colourless, because they have no unpaired d electrons.
in [FeCl4]2- has no unpaired electron therefore it is colourless
