Just a basic color edit to the current no entry overlay in order to provide a blue version for blue spawns and a neutral one as a means to indicate one-way paths to players if all teams have access to said path.
Depending on how its used will depend on how annoying or distracting it'll be to players, so I have some in-game examples from Mann Mall!
I've also provided a vmf for anyone who's not sure how to implement the neutral one, as I have it setup as an illusionary in the map, so that it appears but doesn't block anything.
