根据从绑定接收到的数据，在XAML中更改颜色StackPanel

我想改变StackPanel的颜色，根据数据1，2，3。。。从绑定值接收，我应该使用哪个

<StackPanel Grid.Column="1">
   <Border Height="50" Width="Auto" Margin="3" Background="Black">
      <TextBlock FontSize="18" FontWeight="Bold" TextWrapping="Wrap" Foreground="White" 
                 Text="{Binding valor}" VerticalAlignment="Center"
                 HorizontalAlignment="Center"/>
   </Border>
</StackPanel>

我通过在类中创建一个新变量并在xaml后台={Binding customBackground}中调用这个新变量来修复它

public object customBackground
    {
    get
    {
    if (color == "1")//GREEN 
        {
            return new SolidColorBrush(Color.FromArgb(255, 7, 166, 45));
        }
    if (color == "2")//RED
        {
            return new SolidColorBrush(Color.FromArgb(255, 230, 5, 10));
        }
    if (color == "3")//BLUE
    {
        return new SolidColorBrush(Color.FromArgb(255, 6, 102, 210));
    }
    if (color == "4")//YELLOW
    {
        return new SolidColorBrush(Color.FromArgb(255, 189, 211, 3));
    }
    // Color por defecto
    return new SolidColorBrush(Colors.Gray);
    }
    }
