I agree on the yellow wirenuts..
I'm not sure if that top black is a conductor, or a uncut ty-wrap.. If you look closely at the breakers, it's hard to tell if the top breaker is really a breaker, or just black plastic trim.. compare with the trim in the right panel..
note the absence of writing on the top "breaker".. if you assume that the top black "wire" isn't a conductor, the rest of the colors match up with the phase order in the right panel..
red, black, blue, red, black, blue, etc..
