<color name="lightBlue">#ff6691c4</color>

<color name="controlBackground">#ffffffff</color>

control_switch_color_selector (in res/color folder)

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:state_checked="true"
        android:color="@color/controlBackground"
    />
    <item
        android:state_pressed="true"
        android:color="@color/controlBackground"
        />
    <item
        android:color="@color/blue"
        />
</selector>
