Coloring every third list element

Coloring every third list element

Hi,
    I am a jquery beginner and I need help with coloring list items. I already know to traverse list elements based on the ID or CLASS. However this one is a tricky question. Here it is; On a web page I have 'n' number of lists (<ul><li>...</li><li>...</li><li>...</li></ul>) since they are generated dynamically. They neither have IDs nor have classes. How do I select the 5th list and color every third element with no ID/class being available? Please, someone help me with this.


Many thanks,
JB
