You can very simple change the background colors and/or add background images to the Magento PT004 default theme. You need PT004 version 22.214.171.124 or newer for this feature. You can download/update it in your account.
For most blocks you have 3 options.
- Use the default theme settings
- Add your own colors
- Add your own images
These 3 options can be used in more than 1 location as I will explain below.
First you go to System > Configuration > Pagayo > PT004
So what can be changed with what?
