For some reason Queen Elizabeth took against blue ruffs. It was her majesty's pleasure that no blue starch be used or worn by any of her subjects. Ruffs actually came in many colors.
They were tinted with vegetable dyes at the starching stage. Colored ruffs are rarely visible in portraits because of later restorers' conviction that all ruffs were ivory. They 'cleaned' the neckwear until the offending color was gone.
There are no vintage postcards in this post but it is definately quirky:)
