Hi Maurice! You can change the background colour of the entire page through the “Page Properties” tab on the right. See below for reference:

If your trying to change the background colour of a specific page section simply select the section and adjust the colour through the “Properties” tab:

Keep in mind if you have a image set as the background you will have to remove it in order adjust the colour.

Hey Maurice - to add to Johnny’s comments, I published a screencast a while back demoing exactly how to work with page backgrounds in various templates.

You can check out that video here.
