Not an issue, just a question.

How would I change the background color to something like a green screen

You can change this line:

flitter/src/colors.ml

Line 16 in 16f26a1

 let default_bg = A.(bg (color_of_hexstring "#2f3542"))  

In the future it'd be nice to make the color scheme configurable for sure. Also the default colorscheme is kinda ugly not gonna lie.
