Product colour of the future

My parents recently repainted their kitchen and my mother, who is famous for her lack of artistic talent, chose the paint colour, a cool grey (although can it be called a colour?).  I have to say, she's pulled an absolute blinder, as the grey she has chosen seems to compliment everything put against it incredibly well.  So it got me thinking, as I have said in previous posts, eventually our current obsession with black or white products will wane, so what then?  I would suggest this and will be using it in the not too distant future.  The future is bright, the future is grey!
