How can I recolor any object?

Is there any way to apply a tint to any actor in my scene programmatically or through blueprints?

We want to be able to mark any actor arbitrary actor in the game world but want to do it in a way that doesn’t require this to be taken into account when authoring each and every material.

I can’t come up with anything but it seems like something that might be possible.
Any ideas?

One way is to use a color ID mask as a way to assign or change colors. Just a thought
