Determining Different Highlights Based On Actor Type

I was wonder if it was possible to differentiate between different types of actors in the scene to add different post processing highlights. What it boils down to is I want AI enemies that are threatening to be highlighted in red when at a chosen distance, but have interactive objects(not enemies) come up with a blue highlight.

I got the post processing to work in game, but only 1 color. I made a BP for the individual objects so that when I bring them in game they automatically come in with the close proximity highlighting active so I dont have to do each object individually. I’ve only just started to get serious with Unreal 4 and have very little C++ experience so I am hoping to do in BP.

Thanks in advance

Pretty much like this right?

I’ve sewn it being done with HLSL but with blueprints I don’t know.
