Portal Themes 
A portal theme defines the visual appearance of the control elements, font size, colors, and contrast of the user interface elements of a portal desktop. A portal theme does not define the layout, structure, or contents of a portal desktop. This is defined by the Classic Framework Page (see Classic Framework Page).
Neither the framework page nor the portal theme are directly assigned to a user. Combinations of framework pages and portal themes result in portal desktops. Portal desktops are assigned to users. See also Portal Display Rules (Rule Collections).
You can develop your own portal themes by using one of the theme templates provided by SAP (such as SAP Chrome or SAP Streamline) for:
Changing the color scheme of the portal
Changing the font type and size
Including your own company logo
For an overview of the themes delivered with the portal, see Portal Themes in the Standard Content Delivery.
