Android – Change background of the ActionBarSherlock alone. Not the Tabs

I used this code to change the Color of ActionBarSherlock:

    <style name="Theme.MyTheme" parent="Theme.Sherlock.Light.DarkActionBar">

    <!-- set style for action bar (affects tab bar too) -->
    <item name="actionBarStyle">@style/Widget.MyTheme.ActionBar</item>
    <item name="android:actionBarStyle">@style/Widget.MyTheme.ActionBar</item>
    <!-- define text style for tabs -->
    <item name="actionBarTabTextStyle">@style/MyTheme.ActionBar.TabText</item>
    <item name="android:actionBarTabTextStyle">@style/MyTheme.ActionBar.TabText</item>
</style>

<style name="Widget.MyTheme.ActionBar" parent="Widget.Sherlock.ActionBar">

    <!-- define background for action bar (sets default for all parts of action bar - main, stacked, split) -->
    <item name="android:background">#blue</item>
    <item name="background">#blue</item>
    <item name="android:titleTextStyle">@style/MyTheme.ActionBar.TitleTextStyleWhite</item>
    <item name="titleTextStyle">@style/MyTheme.ActionBar.TitleTextStyleWhite</item>

    <!-- set background for the tab bar (stacked action bar) - it overrides the background property -->
    <item name="android:backgroundStacked">#grey</item>
    <item name="backgroundStacked">#grey</item>
</style>

<style name="MyTheme.ActionBar.TabText" parent="Widget.Sherlock.ActionBar.TabText">
    <item name="android:textColor">#black</item>
</style>

<style name="MyTheme.ActionBar.TitleTextStyleWhite" parent="@android:style/TextAppearance.Holo.Widget.ActionBar.Title">
    <item name="android:textColor">#white</item>
</style>

as suggested by Jake Warton here:

Change ActionBarSherlock background color

But the thing is the ActionBar and Tabs both change to Blue color. I actually want to change The top actionBar background to Blue and Tabs background to White

how to do this?

Thank You
