There isn't any specific "Indian look" - Indians can "look" like Chinese, Burmese, Thai, Europeans as well as the common South Asian appearance. Hair colours vary from black, brown through light brown. Eyes - every shade known to man. I am a Hindu Gujarati and my DNA haplotype is R1a1 - which is found from Eastern Iran to India and our ancestors came via Russia. I have grey eyes and look very European (as do many in Pakistan and Iran)  it is entirely possible that Jinnah shared a similar gene.
