Can I get different colour variations on my emojis?
No, you can't get a purple gorilla or a blue banana. Those changes in colours aren't supported by Unicode.
However, we do have system-level support for different variants of skin-tone and colours of heart. So for example if you own a Yat with a heart in it (), you automatically own the same Yat with all of the different colour variants as well (🤎🤍)!
