Ubuntu 18.04 LTS ships with all-new color emoji for use in messaging apps, text editors, and also on the web. Emoji is nothing new for Ubuntu. Older versions of Ubuntu come with simple black-and-white emoticons.
Starting from Ubuntu 18.04, Noto Color Emoji font, which is the same emoji font is used in recent versions of the Google's Android operating system. These are open source Unicode emoticons whose source images can be found in the Noto Emoji GitHub repository.
For some reason, if you prefer the older emoji and would like to uninstall the colored counterpart, you can follow these few simple steps. Note that the change is reversible, meaning in future if you want the color ones back, you can do that too!
