I was fortunate this May to get some video of this bear while hunting. It was different shades of blue/black depending on how it was standing. Used snapshot to take pics off video file too large to post.
Found some more info on these bears...
What is the rarest color phase of American black bears?
While white is the rarest color phase, a very uncommon and particularly beautiful color phase of the black bear is the blue-gray or glacier bears of southeastern Alaska, northwestern British Columbia and the southwest Yukon. The undercoat of the glacier bears is a rich blue-black, while the outer guard hairs are long and white (or light yellow) with silver tips. This color variation probably evolved during the last ice age when populations were isolated along the unfrozen sections of the coastline, due to the biological process of genetic drift (random fluctuations in the genetic composition of a small population). The blue-gray color is ideal camouflage against the backdrop of frozen ice - the bears are nearly impossible to spot unless they are moving. Unfortunately, this color phase is on the decline. Immigration of non-glacier black bears and emigration of glacier bears across the now unfrozen landscape, are causing the gene frequency to be eliminated in the face of more dominant color phases, as the two mingle and mate
