Show Feature Name on Product Listing

I have some features such as brand and colour set to show on the catalog pages/product listing which works fine but when they appear they show like this “Nike / Red”.



Does anybody know how I can get them to show along with their feature names on the product listing, e.g “Brand: Nike, Colour: Red”;



I know it likely I will need to override the products_list.tpl file but I've had a look and I can't work out how to bring out more info, the smarty tag just seems to bring them out as a one variable.



Thanks
