Color coded light indicator -script and hardware, suggestion?

[bordeb]

On the basis of the experience with this great software that is so usefull in everyday life, as well as following advanced setup - smart home example from the author @jamorham https://jamorham.github.io/ I would like to ask for the suggestion about color coded light indicator, a RPi script that is good in combination with python-usb-wixel-xdrip and hardware (lights, leds) for RPi.
Edit: To clear possible misunderstandings, I forgot to emphasize that the script shoul be able to read BG data from NS or directly from xDrip+.
Thank you in advance.
