hi. How can i change the background color of where my products are shown. Im using prestashop 1.6 and my url is miamipartysupply.com. for example on the following page youll see my products listed with a light gray background. 

 

http://www.miamipartysupply.com/carnival-game-rentals-miami-30

 

i would like to see how i can change that background color as well as all the other background color thats gray on that page including the body, header, and footer, and within the product listed.

you can change it via custom css . for products use the selector

.product-container{background:color}

And for footer use

footer#footer{background:color}
