I believe you're looking for something like this:

	if(UnitIsTapped(unit) and not UnitIsTappedByPlayer(unit) or not UnitIsConnected(unit)) or not (unit == 'target') then
		self:SetBackdropColor(0, 0, 0, .8)
	else
		local r, g, b = UnitSelectionColor(unit)
		self:SetBackdropColor(r, g, b, .5)
	end

I use this to set the backdrop of my frame to that color, though you could do it to other frames. I believe that was originally written by Haste, or something like it.
