Update inverter.sh 

Removed unnecessary if statement and unnecessary /dev/null redirect on line 19
Line 26 can use argless printf rather than echo -n
Error verbose prints in red and to STDERR rather than to STDOUT
Textually replaced compton with picom where applicable.
Removed unnecessary semicolons after exit commands

I might've missed/screwed something but lets hope that isnt the case 😎
