Let's say I have a custom GIF emoji :alert: with multiple colored versions.
Is it possible to assign those a different skin tone modifiers to avoid creating multiple emojis with different names, e.g. :alert::skin-tone-2: instead of :alert_blue:, :alert_green: etc?
I've tried naming it :alert::skin-tone-2:, but got an error Names must be lowercase, and can’t contain spaces, periods, or most punctuation. Maybe there's another option?
