Confused about the list() function

Hi, I have the following situation. I have an array of colors that I would like to print out. My first course of action would be to convert the array to a string so that I can parse it. My command would be: $color_list = explode(",", $color); Now that I have a string of colors delimited by commas, I would like to parse the string and print out all my colors. I have read the documentation on using the list() function but I find it confusing. Can someone clear the fog from my mind please? Thanks, Don
