I have the Philips Hue color lights and I'm very happy with them so I thought I'd share how I have them set up with F.lux on my Windows desktop computer and my Amazon Echo in the event anyone reading this might benefit from it.
So I have the Philips Hue lights programmed to turn on automatically when the sun sets through an If This Then That recipe on www.IFTTT.com. The recipe works with the Weather Channel and it knows my location so once the sun sets, it then triggers the Philips Hue Channel to send instructions to my Philips Hue bridge, which turns on all the Philips Hue lights in my apartment. The color of the lights is the standard bright white that those lights emit if a color isn't chosen, but that's okay (for me) since it's just providing light when walking in the door.
Once inside, though, I turn on my Windows desktop computer and F.lux overrides the system and changes the color of the lights to what can only be described as a soothing yellow/orange glow much like that soothing glow of a Himalayan salt lamp. (I have no idea how it does this, but I'm very happy with it and it's very relaxing. And it even dims as the night progresses.)
The problem I encounter, though, is that I don't always have my computer on, so once the computer goes to sleep or turns off, the Hue lights then remain at that level of brightness until I change them or turn them off. It's not a big deal, but after reading this forum and learning that red light doesn't affect our circadian rhythm like blue and green does, I made another recipe on IFTTT recipe for a darkroom mode. The Amazon Alexa Channel listens for my trigger word, which is darkroom, and it instructs the Philips Hue Channel to change the color of all my lights to red. (The Philips Hue Channel allows you to name a color as well or use a CSS hex code. I tried a variety of them and settled on this one: #A00000.)
So now, about an hour before going to bed I tell my Amazon Echo: "Alexa, trigger darkroom." And she changes all the lights to red. I feel the difference just like someone else mentioned here about how it made them feel and that's now my nightly routine. But hopefully, once F.lux becomes fully functional I won't have to do this and it will just take care of it all.
