If you are talking about changing the hex colours for the warden side to red as well, then this mod does not do that, unfortunately. Such a mod can be made, and has been made in the past, but it needs to be constantly maintained, and it has not been. So currently, such a mod, that is also updated, does not exist.
If you are further interested, you can find us on the Foxhole Modding Discord to discuss getting such a mod made or for information on how to make it yourself.
Good luck!
