Actually, I was thinking about that too. In fact, what if a user 
is using a "classic" dark-background theme on macOS's terminal? 
Or another terminal which by default uses a dark background, like 
the one mentioned above? He would get all the colors and the text 
contrast messed up if I put a different color scheme for macOS 
only. The only valid option would be to check the background 
color of the terminal, but I don't think that's possible at all 
in a standardized way, unless someone can prove me wrong. That 
would be cool.
