The background color flash doesn't show up when displaying a TOP in the background.

[franklin113]

A naive implementation could be:
`

	par_color 			= '{}*'.format(parColors)
	over_ride_color 	= parent().pars(par_color)

	
	# disabled top backdrops for a moment
	ui.panes[0].showBackdropTOPs = False  

	# change background color (0.1, 0.105, 0.12)
	ui.colors['worksheet.bg'] 	= over_ride_color
	
	# reenable the background tops in the delay script
	delay_script 				= "ui.colors['worksheet.bg'] = args[0]\nui.panes[0].showBackdropTOPs = True"
	
	# want to change the background color back
	run(delay_script, self.Defaultcolor, delayFrames = self.Flash_duration)		

`
