Why do people like green anon in porn?

Like, I kinda thought the point of anon was self insertion, but sickly green vs grey puts you further away I thought. I know the origin of it, but in porn it just doesn’t make sense when you have a viable alternative. >:V

For comics and stories, jokes, and regular pics, sure, but porn?

Why not just use grey? TT^TT It’s so much more compositionally pleasing. XD
