I am using a number of circle frames on a white background. I see how to change the color of the frame itself but is it possible to be able to apply a different light color within each circle itself? If not I think this would be a good idea. This should also work with other frames in Prezi
that is not possible currently, sorry. Except with images that would have to be prepared with some graphics software and inserted into the prezi.
To set a picture (or color) of background of frame is a good idea! My students ask about this very frequently.
