If you have multiple ISNs, you may find that it is difficult to quickly identify which is which when looking at most pages in the ISN. Now, we have the ability for you to add a little splash of color to each of your ISNs, identifying each one with a color of your choosing that shows up just beneath the navigation bar.
First, navigate to Settings -- Company Settings.
Then, scroll to the bottom of the Company Settings page. Just above the 'Save Settings' button, there is a square next to a field that is labeled "ISN Color Identifier"
Set you color and click Save Settings
