Add color selection feature

I have a osCommerce online store. I want to add a color selection function for the product at this page: [login to view URL];osCsid=bdd87da0d92215d4a4f88151aeddb17b It should asks me to input the available colors when I add a new product at the admin panel, and reads it in the data base. At the product info page, it will allow users to select color. When user click add to cart, the selected color should shows up on the shopping cart page. When check out is completed, the selected color also need to show up on the orders at the admin panel. Thanks
