colour blind

We'd have to change all kinds of signal systems. No more red lights. Oh, what would happen to the red-light districts? Would be hard to tell different flags apart at car races, or the flags of different countries. flowers would not be as pretty anymore. Food would not look as good anymore - maybe we'd all get to be quite slim in a while. it doesnt matter if you are one of the few people left that still owns a black and white Tv set. Footballplayers may confuse their own team-players with the opposition. navigation at sea would be hazardous - on what side of this bough were we supposed to sail? but i guess we'd be able to fix most of this stuff pretty fast, so we would be all right I think.

I think everyone would be wearing very mismatched clothing. Also makes you wonder if rascism would end. We would all be the same color.

there were no need to invent colour display screen.
