For example, click on the Detail section in the form.
Then right-click and select properties. In the Properties window, scroll down until you see the property called Back Color. Then click on the text box to the right of the property. A button with 3 dots should appear, click on this button.
Then select the color that you want to display. The number that is currently select is probably something like this: -2147483633.
Select the color that you want (even if the color that you want is already selected). Then click on the OK button.
The value should now display as a positive value such as 12632256.
You will need to do this for each page header/footer, form header/footer, detail section, etc.
