Can I add options, such as color, to my items?

Let's say I sell pens. If I put a pen on my site, I want users to click on the item and then be shown a list of possible colors. How can I do this with Zen Cart?

When I view my product, I want it to have a "Buy this in blue" or "Buy this in red" option.

Thanks,
BP
