How to automaticaly turn off f.lux

[Guysmo]

Hi,
I'm often switching between games and movies and each time I need to click on "disable until sunrise" to get default colors.
So I made a little script in AutoIT who disable f.lux when I started a specific application.

Question : To get default colors without click on "disable until sunrise", I need to kill f.lux process but app crash at this moment 3 times on 5. Is there any command line in DOS to properly disable or use f.lux ?

I would like to propose an idea for future version : Make some actions (disable f.lux, turn in movie mode ....) when specifics applications are launched.

Thanks
