I've been wondering if there was a reason for those tiles to be yellow. Sure, it allows non-blind people to spot mistakes more easily, but it also seems that those wouldn't have been used as a decoration in the first place if they had been available in different colors (that said, never underestimate human dumbness).
I've also been wondering at the material those are made of. I am used to white, plastic dots, and I find them slippery when it rains, which is a bit dangerous, since they indicate danger area (they can get especially slippery/dangerous with roller blades, but that's not a great idea when it rains, altogether).

- jcranmer 10y agoIt depends on your definition of blindness. About 10-20% of the US population self-report vision problems. About 20-30% of them reach the definition of legal blindness, which is vision that cannot be corrected to above 20/200 in at least one eye. About 20% of that population are totally blind, which is to say that they cannot even perceive someone shining a light in their eye. In the US, that amounts to about 200,000 people.
