Apart from using the preset themes, is there a way to manually change all the colors of topics and sub-topics throughout a Prezi or would I have to manually change each one everywhere throughout the presentation?
You can change them easily by using Presets.
You can either select a colour available with your template:
Or you can add your own color to the presets by following these steps:
Edit the (sub)topic’s cover color
- Select the (sub)topic
- Right click your mouse to access the pop-up menu and scroll down to select Update style preset
- You can now select this color from your presets at any time!
