Question : Simple car-like color picker

I'm trying to code a simple shopping cart, problem is that I have run out of ideas as to how I can create a color picker like the one you get when selecting the color of a car. A simple set of colored squares that when clicked will change an image and send the information about the color when the form is submitted.

I hope I'm being clear, feel free to ask any questions.

Cheers

Answer : Simple car-like color picker

Here's a simple html and javascript model using t-shirts as an example of a product you might need to choose a color for.
