We still use the Swastika as a religious symbol. Like for Christians it is the cross, from Muslism its the crescent, for Hindus its the Swastika.
From whatever I have read, the original Aryans weren't blond at all. The Vedas dont describe them as blond. The Vedas describe the "Arya" as wheatish coloured skin. The Vedas are probably the oldest book of the Aryans.
The skincolour fits with what I know. I thought they were blond and darkeyed as well, though. Neato. The Vedas are definitely on my reading list. This just clinches it.
