If you want to recover from the effects of EMR then go into nature as much as possible. Avoid man made every thing.
The eye is an ultra sensitive radiation collector. Sadly it seems sensitive to EMR from man too. Half the population have eye problems. It was evolved to ID every frequency in the visible range from great distance. It does not ID any other frequencies. Strangely by eyes react to MWs and every thing goes silvery when I go into strong phone signals.
I think that colours will have no effect on recovering from EMR but getting away from it will. I am making another sleeping sack from anti EMR cloth and suggest you do to. They are the most cost effective solution to EHS.
