Part of the confusion is that the shutter's a nested widget. That is, 
the "shutter" is the entire thing (i.e. the container) and so changing 
its background color isn't usually going to have much visible effect.

At the next level down are a number of shutter items, each of which has 
a short, wide button that the user clicks to "raise" or "lower" that 
shutter item, and a content area that contains the rest of the stuff for 
that shutter item (usually, but not always, a collection of buttons). 
You can access the button and content area for a shutter item using the 
FXShutterItem#button and FXShutterItem#content instance methods, 
respectively.

So to change what I think you're calling the "shutter" background color, 
you actually want to change the background color for the content area in 
the shutter item of interest, e.g.

     shutterItem.content.backColor = FXColor::Black

If you want to change the background color for the "short, wide" button 
for a particular shutter item, use:

     shutterItem.button.backColor = FXColor::Black

If you want to get at one of the widgets inside the content area, you 
can of course do that too; e.g., save a reference to that widget when 
you add it to the shutter item:

     # Create the shutter
     shutter = FXShutter.new(...)

     # Create a shutter item inside that shutter
     shutterItem = FXShutterItem.new(shutter, "Short & Wide, that's me")

     # Create some regular buttons inside this shutter item's
     # content area
     btn1 = FXButton.new(shutterItem.content, ...)
     btn2 = FXButton.new(shutterItem.content, ...)

     # Change button 1's background color to black
     btn1.backColor = FXColor::Black

I'm not sure if this covers what you were asking; if it didn't, please 
follow up.

Hope this helps,
