Well, that's what they are. You can reverse search that image and find they're Kristang people (dressed in traditional Kristang clothing).

Some native Malays look very dark so I'm not surprised by how dark they are. It should also be noted that this ethnic group may have East Indian ancestry as well. Regardless, what would you classify them as/where would they pass in?
