Android : How do you set the title color for the new Toolbar?

I'm using the new v7 Toolbar and for the life of me can't figure out how to change the color of the title. I've set the @style of the Toolbar to a style declared in styles.xml and applied a titleTextStyle with a textColor. Am I missing something? I'm coding for Lollipop but testing currently on a Kitkat device.

styles.xml

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="@style/Theme.AppCompat.Light">
        <item name="android:windowNoTitle">true</item>
        <item name="windowActionBar">false</item>
    </style>

    <style name="ActionBar" parent="Theme.AppCompat">
        <item name="android:background">@color/actionbar_background</item>
        <item name="android:titleTextStyle">@style/ActionBar.TitleTextStyle</item>
    </style>

    <style name="ActionBar.TitleTextStyle" parent="@style/TextAppearance.AppCompat.Widget.ActionBar.Title">
        <item name="android:textColor">@color/actionbar_title_text</item>
    </style>

</resources>

actionbar.xml:

<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/toolbar_actionbar"
    android:layout_width="match_parent"
    android:layout_height="?actionBarSize"
    style="@style/ActionBar"/>
