Toolbar textcolor won't change

I'm trying to change the textcolor in toolbar to white but the color wont change.

Things i've tried:

1- Changing the app:theme=app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"

2- trying to do it programmatically: toolbar.setTitleTextColor(0xFFFFFFFF);

3- The last one which code appears under:

Custom style: ToolBarstyle:

Res/style

  <style name="ToolBarStyle" parent="Theme.AppCompat">
        <item name="android:textColorPrimary">@android:color/white</item>
        <item name="android:textColorSecondary">@android:color/white</item>
        <item name="actionMenuTextColor">@android:color/white</item>
        <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
    </style>

Res/Layout

   <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        app:theme="@style/ToolBarStyle"
        app:popupTheme="@style/ThemeOverlay.AppCompat"
        app:layout_collapseMode="pin" />

Java file:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    /* Toolbar */
    getSupportActionBar().setTitle("Nostrils");
    toolbar.setTitleTextColor(0xFFFFFFFF);
    // Back icon
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    initNavigationDrawer();
}

Change your toolbar to

 <?xml version="1.0" encoding="utf-8"?>
     <android.support.v7.widget.Toolbar
       xmlns:android="http://schemas.android.com/apk/res/android"
       android:layout_width="match_parent"
       xmlns:app="http://schemas.android.com/apk/res-auto"
       android:layout_height="?attr/actionBarSize"
       android:background="@color/colorPrimaryDark"
       app:popupTheme="@style/AppTheme.PopupOverlay"
       android:id="@+id/toolbar">

        <TextView
           android:layout_width="match_parent"
           android:layout_height="wrap_content"
           android:layout_gravity="start"
           android:textSize="16dp"
           android:textStyle="bold"
           android:maxLines="1"
           android:ellipsize="end"
           android:textColor="@color/white"
           android:layout_marginRight="?attr/actionBarSize"
           android:gravity="center"
           android:id="@+id/welcome_textView"/>

     </android.support.v7.widget.Toolbar>

Access this textView

    Toolbar toolbar = (Toolbar) view.findViewById(R.id.toolbar);
    TextView textToolHeader = (TextView) toolbar.findViewById(R.id.welcome_textView);

    textToolHeader.setTextColor(getResources().getColor(R.color.your_color));
