TextInputLayout - Change floating label hint color if EditText is not empty and not focused

Res state - hint color black, good

Focused state, empty - hint color gray, good

Focused state, not empty - hint color gray, good

Res state, not empty - hint color black, not good, should be gray

How to change hint color if editText is not empty and not focused?

This is my current code:

<android.support.design.widget.TextInputLayout
    android:id="@+id/email"
    style="@style/AuthInput"
    android:layout_marginTop="32dp"
    android:hint="@string/hint_email"
    android:inputType="textEmailAddress"
    android:theme="@style/AuthInput"
    app:hintTextAppearance="@style/TextAppearance.App.TextInputLayout">

    <EditText
        android:id="@+id/edit_email"
        style="@style/AuthEditText"
        android:inputType="textEmailAddress" />
</android.support.design.widget.TextInputLayout>

and styles:

<style name="AuthInput">
    <item name="android:layout_width">match_parent</item>
    <item name="android:layout_height">wrap_content</item>
    <item name="android:textColorHint">@color/black</item>
    <item name="android:paddingLeft">0dp</item>
</style>

<style name="TextAppearance.App.TextInputLayout" parent="@android:style/TextAppearance">
    <item name="android:textColor">@color/inputHintActive</item>
</style>
