Does anyone know what this add-on is called?

A greeting for the entire Warmane community, ask if you want to know the add-on that allows you to change the color of the player's frames as the target. I leave an image where you can see what will change in a black color, unfortunately there is an achievement that has not been even better.



PS: My English level is regular, sorry if there is an error.

I've already found it, I close.
