That is correct. On the NW corner of FWA and W169 they are grey/blue.
But also on the SE corner of FWA and W170 they are bright red.

Such information is important for the navigation apps for visually impaired people. Accurate tags of those tactile plates helps people with low/no vision better orient themselves.

Hello.
Please don't "experiment" on the live OSM map. It is used by thousands of data consumers and it is inappropriate to perform test edits there.
If you want to practice, buried in Vespuci's settings you can change it to point to sandbox OSM server rather than the live one.

Hello.
Could you please elaborate why did you tag some of these curb as not having tactile pavings when they are clearly visible from the satellite imagery, and would be on the ground while you were surveying?

It is my understanding that this intersection was named after this event https://en.wikipedia.org/wiki/1996_shootdown_of_Brothers_to_the_Rescue_aircraft to spite Cuba since their consulate is 2 buildings over on Lex Ave.

Hello.
Please note that all the tag values should be in lower case (unless it's a proper name). So in this case it should be "red".

Hello.
Please note that if there are multiple colors, they should be listed using ; not ,
Additionally, multi-word tags are separated using _ not space.

Hello.
What kind of place is this?

Hello.
Rather than just outright deleting data, it's better to use lifecycle prefix such as disused: as documented in disused:*=*

I updated it. Feel free to add other, appropriate tags that you think will be useful.

Hello.
I see that this feature is already mapped as "Added Value Community Garden". Is that not accurate?

Hello.
Would a gas station & car repair shop be more suitable as "industrial" or "commercial" rather than "retail"?

Hello.
What criteria do you use to decide if that landuse area should cross the street like in 128975618 or create a separate one?
Also shouldn't such areas be mapped closer to the property line, "inside" of sidewalks, rather than extending all the way to the curb?

Hello.
In this edit you modified some features in RI and in PA. That makes it difficult to review edits to spot any potential issues. Please try to group your edits into smaller geographic areas, such as neighborhoods or cities or counties, at most.👍
