Color orders

Hi,

Is there a way to add some background color between the rows of the orders, so that it can be easy for the reader to separate the rows of the orders? I know the identifies is the order id, but this will make it much easier, especially if the order entries are a lot.

For example:

Order #10 = Its rows to have bg color : red
Order #11 = No bg color
Order #12 = Its rows to have bg color : red
Order #13 = No bg color

and so on

thank you!
