How to set background color for tool bar

For the nav arrow you can use this to change the tintColor

    <style name="CustomToolbarButtonNavigationStyle" parent="Widget.AppCompat.Toolbar.Button.Navigation">
        <item name="android:tint">@color/red</item>
    </style>

For the overflow button:

    <style name="SampleActionOverflowButtonStyle" parent="Widget.AppCompat.ActionButton.Overflow">
        <item name="android:tint">@color/red</item>
    </style>

For the dropdown you can change: PTToolbarSwitcherButtonTheme

    <style name="SampleToolbarSwitcherButtonTheme" parent="PTToolbarSwitcherButtonTheme">
        <item name="textColor">@color/red</item>
        <item name="iconColor">@color/red</item>
    </style>
