Visual Studio 2010 - How to fix C# WPF Tab Hover Color to NOT change color when Tab is set to background custom color?

In my Visual Studio 2010 C# WPF Application, I have 7 tabs with alternating colors which is what my client needs. They do not like the Hovering over the tab with a mouse and having the background color of the tab change even though the tab is not getting selected.

Partial WPF XAML Code for Dialog looks like the following: 

.
.
.
<TabControl Width="auto" Height="auto" Name="MyTabs" SelectionChanged="MyTabs_SelectionChanged">
   <TabItem Header="Tab 1" >
      <TabItem.Resources>
         <Style TargetType="{x:Type TabItem}">
            <Setter Property="Background" Value="LightGreen"></Setter>
         </Style>
      </TabItem.Resources>
.
.
. Tab Contents
.
.
.
   </TabItem>
.
.
.
   <TabItem Header="Tab 2" >
      <TabItem.Resources>
         <Style TargetType="{x:Type TabItem}">
            <Setter Property="Background" Value="LightBlue"></Setter>
         </Style>
      </TabItem.Resources>
.
.
. Tab Contents
.
.
.
   </TabItem>
.
.
.
</TabControl>

If I do not change the Tab Background colors, there is no issue. However for the end user having the Tabs colored helps in the particular application.

My question is how NOT to change the Tab Color when Hovering over the Tab with the Mouse when I need to have custom background colors for the WPF Tabs?

Any helpful hints on how to solve this issue will be greatly appreciated.

Thanks in advance for clues on how to resolve this issue!

    Modify ControlTemplate for TabItem to remove the triggers that affect at mouse over.
    Or remove the trigger by code bind.

    Very nice solution.

    I didn't need the code behind.

    Here's a sample with the Hover Over color change issue solved with 3 tabs that allow Hover Over color change: 

    <Window x:Class="WPF_Tab_Test.MainWindow"
