tbf, the kalash thing is a bit exaggerated. most look light brown like northern indians or gypsies. some of these viral pics are edited such as the top left girl in OP's pic for instance IIRC. There is also some "photographer's bias" where they snap pics of the most white-passing ones with striking blue eyes and skip over the mass of more brownoid types.

I'm Ethiopian Habesha - a minority of us , a handful in my family for example, could pass as almost pure Arabian-Caucasoids but the majority of us are more intermediate, and some more SSA-leaning. I could imagine a similar cherrypicking among us leading people to think we all look like pure Yemenis or something.

the Vedic-Aryans would have been "browned" already before entering India as they would been heavy in Iran_N from passing through and mixing with BMAC which contributed to the Vedic culture as we know it..

>The caste system was based on whiteness,
the caste system probably pre-existed the Indo-Aryans as you don't see it in any other IE groups. There was likely already a IVC caste system - these incoming Vedics likely just superimposed themselves on top of this pre-existing system.
