How to override SolidColorBrush resource defined in a Style?

How to cover SolidColorBrush out of ResourceDictionary in WPF?

ButtonStyle1.xaml

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:PresentationOptions="http://schemas.microsoft.com/winfx/2006/xaml/presentation/options"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <SolidColorBrush x:Key="ButtonBackgroundColor" Color="LightGreen" PresentationOptions:Freeze="true" />
    
    <Style TargetType="Button">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate>
                    <TextBlock Background="{StaticResource ButtonBackgroundColor}">Hello World</TextBlock>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>    
</ResourceDictionary>

ButtonWindow.xaml

<Window.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>                
                <ResourceDictionary Source="ButtonStyle1.xaml" />
            </ResourceDictionary.MergedDictionaries>
            <SolidColorBrush x:Key="ButtonBackgroundColor" Color="LightSkyBlue"/>
        </ResourceDictionary>
    </Window.Resources>
    <Grid>
        <Button Content="Button" HorizontalAlignment="Left" Margin="275,140,0,0" VerticalAlignment="Top" Height="68" Width="159"/>

    </Grid>

I want to cover the color with LightSkyBlue, but it failed. How can do it? Thanks.

This piqued my curiosity so my implementation uses the suggestion of Sinus32(in the comments) to replace StaticResouce with DynamicResource in the Button ControlTemplate. It worked.

ButtonStyle1.xaml

<SolidColorBrush x:Key="ButtonBackgroundColor" Color="LightGreen" PresentationOptions:Freeze="true" />

<Style TargetType="Button">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate>
                <TextBlock Background="{DynamicResource ButtonBackgroundColor}">Hello World</TextBlock>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

ButtonWindow.xaml

<Window.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="ButtonStyle1.xaml" />
        </ResourceDictionary.MergedDictionaries>
        <SolidColorBrush x:Key="ButtonBackgroundColor" Color="LightSkyBlue"/>
    </ResourceDictionary>
</Window.Resources>
<Grid>
    <Button Content="Button" HorizontalAlignment="Left" Margin="275,140,0,0" VerticalAlignment="Top" Height="68" Width="159"/>
</Grid>
