Solutions of the complexes [Co(NH 3 ) 6 ] 2+ , [Co(OH 2 ) 6 ] 2+

Question:

Solutions of the complexes [Co(NH3)6]2+, [Co(OH2)6]2+ (both Oh), and [CoCl4]2− are coloured. One is pink (absorbs blue light), another is yellow (absorbs violet light), and the third is blue (absorbs red light). Considering the spectrochemical series and the relative magnitudes of ΔT and ΔO, assign each colour to one of the complexes.
