bgcolor Set a patcher's background color The bgcolor object sets a patcher's background color. It accepts 3 integer arguments to specify background color in the form red green blue.The bgcolor object's functionality is equivalent to the brgb message of the thispatcher object, and is simply a convenient way to set the background color using one object rather than the combination of loadbang, message, and thispatcher objects.
