Modding Help Race patching

I need help with adding ""hairColorAsBodySubColor" : true" to the .species file of an existing race.
I have tried:
"[
{"op":"add",
"path":"/human.species",
"value": ""hairColorAsBodySubColor" : true"}
]"
But it doesn't work. I can't figure it out.

 

It should be like this:
"[
{
"op":"add",
"path":"/hairColorAsBodySubColor",
"value": true
}
]"
Thanks to u/chofranc, r/starbound user for this info.
