The app theme can be customized by using the styles.xml file in res | values | styles.xml.
The primary color is the color of the action bar. The primary dark color is the color of the status bar. The accent color is the color for FAB. The sample app looks like the following image:
In the preceding screenshot, you can see the usage of primary, primary dark, and accent colors.
