Hi there,
tricky one for static pages. Try this:
1. You would need to use some CSS to remove the Themes ( Customizer > Color > Content ) inside container color.
For your home page you can use:
.home.separate-containers .inside-article {
background: transparent;
}
2. Now remove the Themes padding on that page by setting the Content Container to Contained

3. Now edit each Container Block, and:
3.1 Set the Backround Color
3.2 Set the Padding ( to replace the missing theme padding )
3.3 Set the Bottom Margin eg. 40px
What this does is remove the themes container styling so you can apply to each Container Block.
