Adding color to text in Geometry nodes?

Hi, I wanted to make my text animated in blender and the tutorial i was watching did exactly that but it didn't show how to change the color of the letters, now my dumbass thought I only needed to add the "Set Material" node and connect it but clearly that isn't the case. Does anyone know how to properly change the color of the text?
