The colors of wavelengths are absorbed in decreasing order of wavelengths.

${\lambda }_{\text{red}}>{\lambda }_{\text{yellow}}>{\lambda }_{\text{green}}>{\lambda }_{\text{blue}}$

as$\mathrm{\Delta E}=\frac{\mathrm{hc}}{\mathrm{\lambda }}$

$\Delta {\text{E}}_{\text{Red}}<\Delta {\text{E}}_{\text{Yellow}}<\Delta {\text{E}}_{\text{Green}}<\Delta {\text{E}}_{\text{Blue}}$

${\mathrm{L}}_1 < {\mathrm{L}}_3 < {\mathrm{L}}_2 < {\mathrm{L}}_4$

As the order of ligand field strength provides the order of relative crystal field splitting energies.
