Background is not recognized in triggers

问题

After asking a question here before someone suggested moving it to the XAML, for designer esthetics. Which after reviewing my code I agreed. Since I can change my colors in my color dictionary and not worry about that chunk of code.

So what I've done in my user control was to add a trigger/datatrigger? to the border which accepts the background color.

<Border.Style>
    <Style>
       <Style.Triggers>
           <DataTrigger Binding="{Binding Type, ElementName=AlertWindow}" Value="Caution">
               <Setter Property="Background" Value="{StaticResource AlertBlue}" />
           </DataTrigger>
       </Style.Triggers>
    </Style>
</Border.Style>

Type should be written as follows

<usercontrol:alerts Type="Caution" Title="Careful"></usercontrol:alerts>

Though I'm getting an error that Background is not recognized and after trying multiple different bindings I'm not getting anything.

Note** I am new to bindings and triggers so I've been trying to read through SO and much of what I've found and have tried is not working.

Basically I want the trigger to sort out the different color opportunities for the Border. So there's four Caution, Success, Info and Warning each of which will have their own colors. And I like this method because then I can use these to change more of the usercontrol itself and not have multiple code behind functions to make them more unique.
