indians pretty much have the most diverse native phenotype of any people on earth. many north indians could easily pass as italians, others could pass as middle eastern people such as iranians. some other groups could easily pass as south american latinos/mestizos. in eastern india some of them look like south east asians but i thinkt hat is because of mixing with tibeto-burman people in the past. some other indians in the south look like mullatos but with straight/wavy hair. Tamils are pretty distinct, they look like very dark cacuasoids. majority of them have the same facial features as white people.
In Fiji too, there is quite a lot of Indians there. You can also encounter people with typically Indian names and very Melanesian phenotype (due to mixing there).
