You need to modify the ControlTemplate of the ListViewItem container.

You can copy the default template into your XAML markup by right-clicking on the ListView in design mode in Visual Studio or in Blend and choose Edit Additional Templates->Edit Generated Item Container (ItemContainerStyle) and then edit it as per your requirements by for example changing the Color properties of the SolidColorBrushes:

<ListView ItemsSource="{Binding Path=Items}" SelectedItem="{Binding Path=DataContext.Current" >
    <ListView.Resources>
        <Style x:Key="FocusVisual">
            <Setter Property="Control.Template">
                <Setter.Value>
                    <ControlTemplate>
                        <Rectangle Margin="2" SnapsToDevicePixels="true" Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" StrokeThickness="1" StrokeDashArray="1 2"/>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
        <SolidColorBrush x:Key="Item.MouseOver.Background" Color="Red"/>
        <SolidColorBrush x:Key="Item.MouseOver.Border" Color="#a826A0Da"/>
        <SolidColorBrush x:Key="Item.SelectedInactive.Background" Color="#3DDADADA"/>
        <SolidColorBrush x:Key="Item.SelectedInactive.Border" Color="#FFDADADA"/>
        <SolidColorBrush x:Key="Item.SelectedActive.Background" Color="#3D26A0DA"/>
        <SolidColorBrush x:Key="Item.SelectedActive.Border" Color="#FF26A0DA"/>
