Isn't this idea a rip off of a tv commercial series for Sony tv sets that ran some years ago? I seem to remember paints and tall buildings... but it might also have been for cars, instead.
Even back in the 60s, it was the commercials I remembered and seldom the products. Those girls on desert islands, coconuts, impossibly white sand, footprints, surf, oiled skin - was it cigars, cosmetics, sweets or all of them together? - maybe I'm confusing tv with moments of my own distant life? Whatever, the colours idea isn't new.
