Get Is Standing in Red Circle

[slimwaffle]

Is anyone able to help me out please?
I'm interested in getting a state for if the player is standing in a red circle or cone.
But nothing immediately jumps out to me when searching the wiki.

I'm looking to create an addon similar to wows GTFO addon. That plays an alarm sound when you are
standing in something bad for your health.

Any help would be greatly appreciated.
