Change color of text block in UMG within the Graph

Hey I am trying to change the color of a text block that displays a timer, when the timer reaches the last 60 seconds it should turn red. Everything works apart from the color change, below is the method I am trying, any help would be appreciated.

I just tried to quickly swap the color on one of my text boxes using the same method you’re using and it worked fine.

If you were to attempt that color change on another UMG widget does it work?
