I'm sure there's an easy way to set this global default, but for the life of me I can't find it and I can't find anything online. What I want to do is to set a default color setting for new text frames, that way, whenever there is overflow in a given text frame, I can draw out a new frame for the overflow without having to manually set the background color for that frame each time.
Does anyone know how to do this?
If you go to Window>Styles>Object Styles, you either change the settings for the Basic Text Frame object style to the color you want, or make a new object style, set it's color, and choose that style while the text tool is selected, but no object is selected.
If you do that while no documents are open, that will become the new default behavior of newly-created documents (but won't change existing documents).
