I’m wondering how to change the default colour of text in the question placeholder inside slide master?
Oops, actually not to worry.
For anyone else looking it’s inside the object settings button near slide master & feedback master buttons on the view tab.
There are two ways to change the default text color of questions. You can change it in the Object Settings or change the text color of object placeholders (you have to select the object instead of changing the inline text color).
