In 5.4 you now have the option to change the interface color. This is a great setting, because I am not a fan of the emerald green interface that’s default.
This is a great option, and easy to change.
To change the color just navigate to System – settings. At the bottom under view settings you will see the option to change the theme. There are currently 4 colors available. Green, red, blue, and my favorite Melongene. Good Job Fortinet!
