Topics that seem to be ignored in ICS

I am creating an application that uses several themes for its actions. They all work fine and work on phones with Android versions up to Android, but for some reason, when I apply themes on the Galaxy Nexus (work 4.1) and Nexus S (work 4.0.4), the background is always black.

Here one of the themes I use does not work:

<style name="BlueStyle" parent="@android:style/Theme.Holo.NoActionBar">
    <item name="android:background">@color/Blue</item>
    <item name="android:textColor">@android:color/white</item>
    <item name="android:textSize">16dip</item>
</style>

Blue color is defined in mine res/values/colors.xml. The topic is in res/values-v11/styles.xmland is mentioned in my manifest like this:

<activity
        android:name=".activity.SplashActivity"
        android:theme="@style/BlueStyle"
        android:configChanges="orientation|keyboardHidden|screenSize"/>

, , ( res/values, @android:style/Theme.NoTitleBar ) Android ICS. @color/Blue, , , Activity. , @android:style/Theme.NoTitleBar, Activity , .
