    Have a look at this: http://www.wpftutorial.net/ListBoxSelectionBackground.html or http://dotnetbutchering.blogspot.be/2009/08/how-to-set-wpf-listview-selected-item.html -the same principle applies for the ListView control.

    For example, the following triggers based code should do the trick and imitate no change of colour when the selection is changed.

    <Style TargetType="{x:Type ListViewItem}">
       <Style.Triggers>
          <Trigger Property="IsSelected" Value="true" >
            <Setter Property="Foreground" Value="YourForegroundColour" />
            <Setter Property="Background" Value="YourBackgroundColour" />
          </Trigger>
       </Style.Triggers>
    </Style>

    For also disabling inactive style,

    <Style TargetType="ListViewItem">
        <Style.Resources>
            <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent" />
            <SolidColorBrush x:Key="{x:Static SystemColors.InactiveSelectionHighlightBrushKey}" Color="Transparent" />
        </Style.Resources>
    </Style>

    What I normally do is define that color in the listview's resource collection. Then for each item I can define a template with the colors I like and when I select I don't get the blue.

    I do think you should have some sort of indication that an item is selected though.

    I'm not sure I understand what you mean by white instead of blue. When a ListViewItem is selected the foreground and background is changed by a trigger. To change the foreground of a ListViewItem you can use this

    <ListView ...>
        <ListView.ItemContainerStyle>
            <Style TargetType="{x:Type ListViewItem}">
                <Style.Resources>
                    <!-- Foreground for Selected ListViewItem -->
                    <SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" 
                                     Color="Black"/>
                    <!-- Background for Selected ListViewItem -->
                    <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}"
                                     Color="Transparent"/>
                </Style.Resources>
            </Style>
        </ListView.ItemContainerStyle>
        ...
    </ListView>
    

    Update

    Try this for re-templating. I removed all triggers for selected

    <ListView ...>
        <ListView.ItemContainerStyle>
            <Style TargetType="{x:Type ListViewItem}">
                <Style.Resources>
                    <LinearGradientBrush x:Key="ListItemHoverFill" EndPoint="0,1" StartPoint="0,0">
                        <GradientStop Color="#FFF1FBFF" Offset="0"/>
                        <GradientStop Color="#FFD5F1FE" Offset="1"/>
                    </LinearGradientBrush>
                </Style.Resources>
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate TargetType="{x:Type ListViewItem}">
                            <Border CornerRadius="2" SnapsToDevicePixels="True"

                                    BorderBrush="{TemplateBinding BorderBrush}"   
                                    Background="{TemplateBinding Background}">
                                <Border Name="InnerBorder" CornerRadius="1" BorderThickness="1">
