Honestly, I don't envy those that design and publish emojis, it's a cultural minefield. :-) has no color, gender, outfit or what-have-you. There's been a lot of debate about the skin tone of e.g. the thumbs up emoji (which now comes in half a dozen colors if the relatively ambiguous / non-human yellow isn't to your needs), the gender of emojis depicting jobs, and the color of outfits of emojis depicting jobs.
