The Application Theme (the colours, text colour etc)
In addition to being able to upload you own custom CSS files and images on the Edit Application Details Module, you could also set up the colours of the headings, text etc in the "Edit Aplication Theme" Module. It should already be set up before you access your site.
To view your Application Theme (the colours, text colour etc) click on Edit Application Theme

If you want to change the colours of your theme, please ask your distributor first. Choosing the correct colour combination is best left to the design professionals, and it is easy to make a mistake and have colours that do not work well together.
Now that the style of your site can be updated using the CSS files on the Edit Application Details, it is important that you do not change your site colours until you have checked with your Distributor first.
