The word Aryan and Dravidian are politically debated and their application by europeans, iranians and so many other people only adds to the confusion. Its easier to use Caucasian, but Russians and other eastern white people dont regard them self as such. They use that word to identify those from the Caucas regions - Georgian, Armenian, Azeris - etc.
India has three main groups of people. North, south and north-eastern people. One can distinguish between them by their facial features than skin color, since in this day and age every one is mixing. Northies have prominent caucasian features and many have light eyes. Southies have (typically) aboriginal+ caucasian mixed features. North-easterners are mostly a hybrid mixture of Indians and Chinese.
Now even though Jindal’s parents are from Punjab, north punjabi, he is a bit dark complexioned than the average Punjabi. His wife looks more north indian than him.
