You might be using QuickBooks Desktop before. The option to add shaded alternating lines to invoices and other sales transactions is only available in the Desktop version. 

Although, you can add colors to your templates in QBO. Here's how:

1. Go to the Gear icon and select Custom Form Styles.

1. Click New style, then select Invoice. You can also edit the current template if you want to continue using it by clicking the Edit button under the Action column.
2. Proceed to the Design tab add click Try other colors. 
3. Make the changes to the colors that you want.
4. Select Done.
