What color is the barrier-free floor club block?

It is usually yellow, black or white and blue.

Generally, the signs of barrier-free passages are designed in yellow, black or white and blue, which are in sharp contrast and easier for the public to see. Barrier-free access signs should be set 200 meters in front of the barrier-free access, and there are barrier-free access at the gates of banks, supermarkets and hospitals, which is especially convenient for people in need.
