Does anyone know how to invoke native function to set Windows 10 Night Light option to True ?
Seems like SetDeviceGammaRamp() is the only option.
If so, then how to set the value to pass to the function in order to have reddish screen?

Check [this question](https://stackoverflow.com/questions/8359607/correct-usage-of-setdevicegammaramp) for some relevant information. You would use Platform Invoke (pinvoke) to invoke the unmanaged function from managed code in the same way as any other. – jmcilhinney Jul 06 '18 at 07:03

I would suspect that's your option. I'd guess night light is just a service which does exactly that. – Stevo Jul 06 '18 at 09:23
