@anne_twain @cargot_robbie not all people who could benefit from such signage are 100% blind. The contrast between the white wall and the black sign with white markings is pretty good, making it easier to find.

(this is also why the dots are in a contrast color, to make them easier to find)

@anne_twain There is no expectation for a single accessibility solution to be suitable for everyone. This is impossible, in fact

93% of people with sight loss have some vision.

Yes a multitude of access solutions need to be available to remove the barriers for everyone.

But accessibility isn't a search for one perfect thing and your line of argument isn't the "gotcha" that you think it is. It's just the same tired old line that often keeps any accessibility improvements from happening at all.
