Toggleble keyboard button?

[Ar_0n3]

Hi i have used g366, and becaus i have a g910 i can use a the programabloe key G5 to mute/unmute the mic. My question is: Can i make the button toggle between red(mic muted) and blue(mic unmuted). I have tried using Aurora softwere but it seams to only work on the already locking keys like caps lock, scrol lock and num lock. Is it pausible to "program" this simple action with a script or something? If its possible, any good tips to how to lern how to do it?

I tried posting this on the Logitech gaming subreddit. But got no response

My mic broke and I am now using the blue yeti but I still want this kind of button. 

All response greatly apreaciated
