Facebook Messenger adds 1500 new emoji
The new emoji feature a better and wider representation of women, and more skin tones. Up to now, Facebook Messenger utilised the traditional yellow colour for emoji, but this update adds the different skin tones approved by the Unicode Consortium.
You can set a preference for a skin tone from five options aside from the yellow shade. Once selected, the skin tone will be the default for that emoji from then on. However, you can change your preference at any time from the Settings menu.
