is it possible to have several night window colors?

As far as I know it is possible to have nightwindows with a different intensity but of the same colour (for some this could be set to 0, so that they are effectively switched off). You select the nightwindows you want and set intensity for those ones only.
But I'm not sure if this works for different colours too.
There is a tool that sets nightwindows randmly on and off.
