overlay All 		A routine for the prediction of the colour of the solution from the visible spectrum is available as a menu option in JSpecView. This involved curve fitting standard colour matching functions (CMF) to obtain numerical descriptions of the chromatic response of an average human observer viewing through a 2 ° angle as well as standard illuminant (D65) data and uses the visible spectral information recorded between at least 400 and 700 nm.

prediction of the  solution  colour

As an exercise, superimpose all the spectra, then based on the peak of lowest energy for each spectrum arrange the complexes in order of increasing Δ.
When superimposed, you can move through the individual spectra by using the arrows on the bottom left of the display, To expand or reset the display use the arrows and middle circle on the right hand side of the display
