We also have the odd one. 2 falls in a row, while salmon fishing on the Babine River, we saw chocolate/black sows with 2 year old cubs. Different cows, of course, yet the same colour. Brown backs, black when wet of course, with black sides and hips. Both sows had a silver-tip cub and chocolate/black cub. The first sow had 3 cubs, while the second only had 2.
