I'd like to see that newer research saying that dogs are not as colorblind as originally thought. I've heard that cats also see color.

The black white issue and segregation has absolutely no bearing on the fact that scientists in earlier studies believed that dogs could not see colors i.e. red, yellow, blue etc. As stated in my earlier post, it was because the tests were done improperly and didn't take in account for a dog's incredible sense of smell. Experimenters thought they were training the dogs to react to a certain color, yellow, for example, but the dogs actually were picking up odor cues, such as dyes in coloring or material used, or experimenter's hand scents. When given a red object that was touched by the same experimenter, the dog would choose that because the sense of smell overruled the colors. Once the experiments (YEARS LATER) were done to rule these things out, the dogs showed they could differentiate between colors such as blue, red and yellow.
This thread went in two different directions. I thought you were asking if dogs were colorblind. This means can they distinguish between colors. It has nothing to do with can a dog distinguish between races. There is probably a great deal of research on the topic, but my responses were directed to whether or not a dog can see colors i.e., blue, red, yellow. There is loads of research on this and the answer is yes. As far as being able to differentiate between the races, while I'm not familiar with the research, I don't see why they would be able to do this; and remember, dogs generally bark at the unfamiliar.
