I was a loyal f.lux user for a long time, but now there's really no point.
Additionally, f.lux doesn't (perhaps didn't, I should check the changelog on this new version) take into account OS-native color shifting and (at least on Windows) caused "night mode" to be enacted on top of the OS' own "night mode" leaving me with a... let's just say very drab screen as a result.
I personally prefer the OS doing less, but more stability and better, and allowing me to customize through apps. I feel that over the last few years, Mac OS has gone "wide" with features and has gotten less stable.
I've got a 2012 Mac Mini with Dell display connected over DP, and night shift just works. So at least some non-Apple displays are supported. Not sure what's the difference here.

I ask this as someone whose most recent project is bathed in a deep blue background, while posting on a site that is comfortably orange.
Please please don't write grey on white. It's illegible. I have to ctrl+a all the time. Black on white, like most books. Also take into account that the user may disable websites picking their own fonts. I do this because I don't want to download them fonts for no apparent reason and because it's usually illegibly thin type. Thin type + #ddd color only helps in the process of becoming blind.
Off topic: while at it, I wish pages used the first screenful for more meaningful information.
You could put a switch to enable "night mode" for your website, but if your visitor knows about this problem he'll already have either f.lux installed, or native options enabled.
It’s better to make your design look good (I recommend lots of lightness contrast especially for text, and nothing too outrageously colorful), and leave minimizing blue light exposure to the user/browser/OS.
I don't think that shade of blue is that bad for your eyes. I for instance have a gradient between fuchsia and purple, and it's probably worse.
As long as it is is easy to disable said behaviour. Case in Point: My rather fancy and expensive Dell monitors have got a so called intelligent powersave mode where they automatically power down if there is no activity after a period of time. Unfortunately there is no way to disable this "intelligent" behaviour. Also unfortunately this behaviour is buggy (tested on more than 1 Dell monitor). I can be typing, playing a game or just browsing around and bang, monitor powers down. It turns out the underlying cause is the type of connection I am using to the monitor.
It turns out that this "intelligent" powersave is rather dumb, buggy and best of all can't be disabled because why would anyone ever not need this glorious new feature, right? /s
I actually made the decision to paint the header the same color as the body text. No idea how many people will view the site with flux on but since _I_ need to look at it a lot, I figured it was a good change to make.
In general I think its never a bad idea to reduce strain on the eyes of a user, reducing excessive contrast is one way to do it
I'm not a professional web designer Tho.
I had it set to switch the colors at sunset in my location, which it detected to be at 7:56p. While using my computer late one evening, I wondered why everything was still so bright and obviously not using the appropriate yellow and orange hues. I checked on the Windows settings, it told me Night Light was "off until sunset (7:56 PM)", even though it was 8:52p. So it didn't realize that 7:56 < 8:52, and that it should have already turned on Night Light. f.lux just works, Windows 10's solution does not.
With f.lux you can insert your location manually.
And in general, if I need to wake up early, I'd rather the monitors be at their bluest immediately, and not wait until sunrise.
A fixed schedule is better than the fancy sunset times.
To each their own of course - if it bothers you, don't do that ;-). But from personal experience I can assure you that not everyone minds a reddish screen before sunset (honestly, many visitors don't even notice unless there's some other screen right next to it).
I'd rather just give it to F.lux. MS will use it to sell me Bing search results.
I thought it was something like when websites ask for your location temporarely.
Apple was first (?) to stole the idea from f.lux, and since then everyone else followed suit.
I don't see a lot of people going out of their way to install f.lux. On macOS I use the native option because it allows you to disable it for projectors and similar.
May they manage to find a rewarding and stable business, they've done my eyes and I an important service. Before F.lux, I had strained "computer eyes". It was a drain on my energy and made me grumpy. It is no more.
Ohhh, this explains so much. I uninstalled for the same reason as you and figured it was surprising the program shipped with such a locked-in scheduler as the only option, when there would invariably be a fair bit of overlap between people who'd like to manage their lighting and people who want more custom setups than the incredibly constrained one offered.
I'll look into Lightbulb, I have a piecemeal self-rolled fix - which is usually my favorite solution :P but still worth replacing with a maintained app if one exists.
> Unlike f.lux, LightBulb is optimized to make as little WinAPI calls as possible to prevent FPS drops and hitches. It also allows way more customization, albeit the most intricate settings needs to be changed manually in the config file. LightBulb also offers an option to temporarily pause its gamma control routine when a fullscreen window (like a game) is in foreground.
A good summary can be found in this thread:
> We've improved performance, so f.lux will have much less impact on your system and on games especially.
I've used both Twilight and f.lux (rooted only) on Android in the past and Twilight's defaults are rough and needs too much fuss & attention to get the settings right. f.lux was buggy even tho I was rooted. "Night Light" is OK.
I can only make it come on and off at a certain time, and the color temp is just a slider with no numbers.
With f.lux, I can have day, evening, and night, and it adjusts automatically to my location. When I travel, I have to adjust the time on my phone.
All little things, but it shows how f.lux is polished and Night Shift is not.
My phone is jarring in the evening because it's way cooler than my display.
f.lux may live on as a MacOS and possibly Windows desktop app, but it's pretty much impossible as a mobile app now.
IMO Apple chose the aesthetic of less red shift and traded away the sleep-assisting benefits of a more pronounced shift.
Edit: Apparently this is now built-in to Gnome 3.24+, using the name Night Light. I am happy camper again!
This covers some of the details around it:
The fact that the color change makes drawing a little bit harder may also serve as a gentle reminder to get the fuck off the computer and go to bed instead of staying up until the wee hours of the morning.
I don't believe I opted into any betas, and I couldn't find a similar featureset for Windows/Linux.
Still, good news for anyone running Windows/Linux, I'm actually going to go update ASAP.
Hopefully this fixes my main issue with f.lux. It seems to cause severe input lag during transitions, making my Windows machine nearly unusable.
But I guess now they've made it official.
