Salesforce Colored Favicons adds colored favicons for tab and window headers to help differentiate between organizations. Each organization will have its own distinct colored favicon. You can now see at a glance what organizations you are currently in, what the URL is, and which apps you have installed on your device. You can also now customize your favicon in order to give your website and app a unique identity. The Salesforce Colored Favicons extension supports classic and Lightning Experience domains and includes separate icons for production, sandbox, and scratch orgs. Now you can also choose the color of your favicon for any org you have visited.
