why Aishwary Rai paints herself white self loath

as a Indian guy myself I feel really embarrassed when my white friends ask me that why Aishwarya Rai paints herself white specially when she is abroad Is she embarrassed to have brown skin and brown eyes does she thinks she is too good to have brown eyes and brown skin in most ofter movies she wears makeup 10 shades lighter than her real skin tone and even when she is not on film she still wears white
