I believe that the colour green is meant to be a 'calming' colour, hmmmmm how do you keep several hundred pax calm when their passed out anyway after suffering from dehydration from excessive vomiting?
As awful as this sounds & it's just a mental picture story here how an earth are they going to find again several hundred pax if an A380 crashes into a green grassy field?
Brings a whole new meaning to 'blending in' !
