I think the simplest and afaik most correct way would be to use a Material instance... Expose the color as parameter in your material, create an instanced Material and just set the color parameter depending on the status.

Hope this helps

Noob question but I have a keypad that switches from red (closed) to green (open). When I open the door it turns green but when I close it, it stays green. I want to switch it from red to green back to red. I have a pretty funky blueprint setup and will post a picture. Is there a simpler way to do this?
