You can use VisualBrush for this. Example

<SolidColorBrush x:Key="MyBackgroundColor" Color="Green"/>
<VisualBrush x:Key="RectangleBrush">
    <VisualBrush.Visual>
        <Grid>
            <Rectangle Fill="{StaticResource MyBackgroundColor}"/>
            <Image Source="BackgroundImageSource"/>
        </Grid>
    </VisualBrush.Visual>
</VisualBrush>

<!-- ... -->

<Rectangle Fill="{StaticResource RectangleBrush}"/>
