Why should skin colour be specified at all? Why not leave it as an implementation detail? Yellow is the popular default choice, but it could very well be green, blue, pink, or anything really.

Why are the Simpsons yellow, yet the black guy in the show is black?

There's no "neutral" rather its just "white without specifying it"

[graemep]

That is your perception. What is neutral is cultural, maybe personal.

I grew up in two multi-cultural places so do not have the same default perceptions.

Why should the Simpsons hold any relevance to emoji?

[tehjoker]

why not let people just pick which one they want to use

[F3nd0]

I guess they could just support custom colours, but that seems like a needless complication—much like skin tones themselves.
