Color prejudices of Medieval Hindus

Sanskrit sources are full of snide comments about the ghastly white complexion of central asians. Comparisons were made to the skin of a leper. E.g. Here is an extract from Alice Albinia's "Empires of the Indus":
A Kashmiri Hindu recoiled in horror on beholding the pale Ghurid ambassador:
"It was almost as if the color black had shunned him in fear of being stained by his bad reputation. So ghastly white he was... whiter than bleached cloth, whiter than the snow of the Himalayan region where he was born."
