Background Slide Color

Can the color of a particular slide be set or does every slide have to have the same background color?
Thank you.

As far as I can tell (since I’ve tried to do the same thing), you can only have ONE background color for the entire project. The only way to change the color for a particular slide is to create a file (in Photoshop, etc.) large enough for your working area in the color that you want and place it on the bottom layer. THANKS TO LAYERS in FM4, you can do this!!

Although, it would be a nice addition for the user to be able to change the background color on a slide by slide basis, rather than having to sacrifice one layer (of the currently six maximum) to do it.
