Further to @Ryan:

In the layout for your activities, you can also add the attribute

android:background="@android:color/white"

to set a background color. You can also introduce a custom resource /res/values/colors.xml in which you can declare custom colors. One such file might look like:

#B0171F

You then introduce these in XML as follows:

android:background="@color/fire_brick_red"
