Woocommerce: Changing the variations select default value? [closed]

On the Product Edit page for the variable product, click on the “Variations” tab.
Once you setup variations for the Colour you can set a “Default selection” at the bottom: http://cld.wthms.co/7LIv

This will be the default option selected when a customer visits the page (if it is in stock).
