So I have some XAML like this:

<Trigger Property="ItemsControl.AlternationIndex" Value="2">
    <Setter Property="Background" Value="Red"></Setter>
</Trigger>

How can I set the color Red, to something like 250 200 150? I tried Color 250 200 150, and 250 200 150, but doesn’t work. Any ideas?

    Use HTML-style colors. 

        <Trigger Property="ItemsControl.AlternationIndex" Value="2">
        <Setter Property="Background" Value="#FF0000"></Setter>
    </Trigger>

    Or, if you want alpha transparency:

        <Trigger Property="ItemsControl.AlternationIndex" Value="2">
        <Setter Property="Background" Value="#80FF0000"></Setter>
    </Trigger>

    Or using your example color of 250,200,150:

        <Trigger Property="ItemsControl.AlternationIndex" Value="2">
        <Setter Property="Background" Value="#FAC896"></Setter>
    </Trigger>
