How do I make text readable against a busy background?
Generally to what is making the text unreadable is that the background switches from light to dark over and over. You can use dark text and you can’t use light text. One way to make the text readable is to make it a Text Effect. Text Effects will allow you to add a shadow or outline to the text. Having light text with a dark outline or shadow (or vice versa) will allow the reader to see the text through any busy background. See the text effect section in your manual to learn more about text effects. You can also try making your background lighter or darker.
