Magento Configurable Options

I have a configurable option for Color. I have managed to display the labels (red,blue,green) for it within A tags on the product view开发者_开发知识库 page.

What I want to do is when I click on red tell Magento that I've selected Red and when I click on add to cart it adds the product with the red selection.

I'm not good at Javascript!

Your help will be greatly appreciated.

Thanks.

magento alredy knows what's your selection if you are inserting it as a custom option(see you order in admin)
