Just recalled ;in my early experimenting making CS?EIS,I was trying various power sources.One brew went so dark it was deep coppery brown.I can't remember for sure what source of power I used,but I think it was 120VAC through a resistance.It seemed to be doing OK,but,I had an interruption and forgot it was running.By the time I remembered,it was that deep colour.I was using two Canadian Maple leaf coins and the one looked like part of it had been melted off by a torch.I'm sure there was enough silver in that 1/2 gallon to dilute down and treat all the people in New York.I have had deep yellow for much the same reason using 27/34VDC and being distracted,letting it brew too long.But,I never dumped this as it was yellow but clear.I diluted it with DW and used it topically.
