        <item name="android:textColor">@color/white</item> // doesn't work
        <item name="titleTextAppearance">@style/TextAppearance.AppCompat.Widget.ActionBar.Title.Inverse</item>
        <item name="android:titleTextAppearance">@style/TextAppearance.AppCompat.Widget.ActionBar.Title.Inverse</item>
        <item name="subtitleTextAppearance">@style/TextAppearance.Widget.AppCompat.Toolbar.Subtitle</item>
    </style>

Chances are you are extending from the wrong parent. If not, you can try adding the style to the toolbar layout directly, if you want to override the theme's settings.

In your toolbar layout:

 <android.support.v7.widget.Toolbar
      xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto"
      android:id="@+id/toolbar"
      android:layout_width="match_parent"
      android:layout_height="?attr/actionBarSize"
      android:minHeight="?attr/actionBarSize"
      app:theme="@style/ToolBarStyle"
      app:popupTheme="@style/ToolBarPopupStyle"
      android:background="@color/actionbar_color" />

In your styles:

 <!-- ToolBar -->
  <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="actionOverflowButtonStyle">@style/ActionButtonOverflowStyle</item>
      <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
 </style>
