Unfortunately, no. You might be able to make some good guesses based on the objects in the photographs, but color is three dimensional and in a black and white photograph it is mapped into one dimension. So, for example, a light red and a dark blue might map to the same gray level in photograph and you have no way to tell which color the object was without some additional information from outside the photograph. And unfortunately, knowing about some objects does not tell you about others.
