Is this crab meat cooked? I purchased a small container (8 oz) of frozen crabmeat. I do not know if it is cooked or not. The contents appear to be grey (it's a clear plastic tub).

The container reads: 
Wild Caught Special Crabmeat
Small Pieces of White Meat
Perishable; Pasteurized

There's other writing on the container as well, but I don't think it's relevant.
"Pasteurized" means that it was kept at temperatures below cooking for a prolonged time, which kills most pathogens. Pasteurized food is reasonably safe for consumption without further cooking, provided it has been kept well refrigerated since the pasteurization. 

However, I doubt that the taste will be especially good after just a pasteurization. For the sake of taste, and also to further reduce food safety risks, I would cook it before eating.
