As of now, your iPhone’s emoji keyboard only lets you select a wide range of pale pink hands as well as white boys and girls.
A new beta release of iOS 8.3, currently available only to software developers, has six “skin tone modifiers”. Once released (rumors indicate maybe mid-March) you’ll be able to click and hold on any emoji to change the skin tone. Along with this change comes a few new emoticons, including a ton of new family emojis to cover all different family compositions. There will also be a bunch of new country flags, as well as an update to the old style watch which is now an Apple Watch (of course!).
The new emoji were make possible thanks to a change in the Unicode standard called the “skin tone modifier” which allows users to select the tone of compatible emoji.
