Quite the other way round, excuse the possible off-topicness: As a boy, way back in the sixties, age four or five, one day I overheard my parents talking of 'color tv' and the possibility of getting such a thing. "What is that?" was my obvious question. "A tv that can show colors, of course". "But our tv does do color", I informed them, and was promptly told it didn't. But of course it did. I was adamant. I knew that television was full of colors, and always had been. I could describe the colors of all sorts of things I'd seen on our tv. I remember knowing for a fact that a Volkswagen in some series I had been following was bright red. Stupid parents for not realising. Next time the thing was turned on in all its vacuum tube glory, everything - to my immense disappointment - was greyscale, and remained so for several years until an actual color tv was actually purchased.
