What themes can I use in Fusion Applications?

There are three options:

• Apply the Default theme, which is a Redwood theme and has News feed as the home page layout.
• Create a Redwood theme either from scratch or using the Default theme, and set the home page layout as Home with Ask Oracle or News feed.
• Use your previously saved classic themes, which you can edit using the classic themes editor. You can’t create new classic themes, and predefined classic themes aren't available anymore. To use Home with Ask Oracle, you need to use a Redwood theme.
