F.lux lower than 2700k during daytime
-
Why is it possible to go below 2700k during "nighttime" but not during the day? Is there a solution to be able to get lower values at all times (either via a UI feature or config file)? F.lux is a great program, but it is frustrating being limited as to when you can achieve minimal screen brightness levels.

Unfortunately, the only way to do it is by changing your Location to a place where the sunset has occurred already. Fortunately, this is very easy and takes just a few seconds. Just change the 2nd number.
For example, I'm in Minnesota at Latitude 93.36W. If I make this number higher, then I move further West. If I reduce it, then I move further East. If I change the W to an E, then I simply go to the opposite side of the planet.
Always remember that the sunset will be earlier East of you.

O.K., I think we need a UI change. Limit Daytime to around 3400K and NO LOWER. Seriously, maybe even limit it to the awful look of the over used fluorescent lighting choice of 4200k, and no lower.
Then have a special over ride (Master Color Temperature) setting like Cf.lumen has.

As it stands you actually have the same setup (excluding master color) as cf.lumen!!
Also, I (and many others) would like to know why you, and several others like to use such a warm yellow setting in the daytime. I'm using 4200K right now, and it just feels wrong. Switching to 5000K is so much nicer!
How dark is the room where you want this setting, a window or even a skylight would really light up the room. -
My reason for wanting to use color temperatures warmer than 2700K during the day is, I never know what time I'll be going to bed. I mean, it could be at ANY time during the night or during the day (literally any time at 'night' between sunset and sunrise or any time during the 'day' between sunrise and sunset). I prefer to use 1200K when I'm getting ready for bed, so of course I can't use 1200K when f.lux says it's daytime. So, I have to change my Location to a place where it's nighttime (fortunately it's very easy to do). The only other way I know of to fake nighttime is by changing my computer's time, but changing my Location is much easier.
I personally have no other reason than that to use anything warmer than 6500K during the day. If my monitor is too bright while I'm wake, then I lower my monitor's brightness using its onboard controls. I don't know about anyone else, but I like my color accuracy on my computer during my waking hours. The warmer I set the color temperature in f.lux, the less accurate my color is. Now sure, I have no real NEED for color accuracy, but I still prefer it quite strongly because it looks better to me and I enjoy using my computer more when the color is accurate. I also keep my room well-lit during my waking hours, so I also keep my monitor's Brightness setting at 100.
It's harmful to the human eye to be using a computer without any lights on - where the monitor is the only source of light in the entire room, even at the monitor's lowest possible brightness. Even using the monitor's lowest possible Brightness setting combined with an extremely warm color temperature in f.lux is not a good idea because you're still staring at the only source of light in the entire room. That's not good. It can result in eyestrain, and if you live this way for too long, then it can cause some damage to your eyes that will make you regret doing this later in life. So, I would say that it's critical to make sure the room is well-lit while using your computer.
Anyway, so walwb, I'm wondering the same thing: why do you want to use a color temperature that's warmer than 2700K during the day?

My eyes are fairly sensitive to bright white light and I have gotten used to the monitor at 2700k so the changed colors no longer bother me. Also, I have other sources of light in the room (a lamp next to the computer), so it's not like my monitor is the only source of light. I just think that it is silly that we are not able to go lower than 2700k just because the majority thinks it would be to low for them (I would even be fine with a "secret" setting to get the lighting so low, but having to change your location is just unnecessary).

Well, that's what you're gonna have to do until Lorna and Herf (who are the f.lux team) can add this feature and put it up on the website.

Why does it matter to you? I can't get my head around why you would want to make it harder for someone to choose the setting they like because your personal preference differs.

Why does it matter to you? If you don't like the warmer temperatures, DON'T USE THEM. What is wrong with you?
You're misunderstanding why he said that (it seems to me you're taking it out of context). He's not posting his own opinion in agreement with walwb, he's responding to it and he's responding to the fact that this question gets asked a LOT.

@TwoCables Is there a reason why I shouldn't being using temperatures lower than 2700k during the day? If not, I don't see why those settings (or 4200K and below as timpster suggests) shouldn't be options in the tray, even if they are used by only a very small minority. It's not as if these settings being included in the daytime menu would negatively impact the user experience. It seems they were left out because the developers couldn't imagine someone would want them, for which I don't blame them, but for the sake of functionality this is a decision I am confused by. Again, it's not like they would negatively affect the user experience. Changing locations is little more than a nuisance, and a master setting would be a good feature, I'm just perplexed why someone would want to make it harder, even if only slightly, to use an unconventional setting.
You both have asked why someone would want to use lower than 2700k during the day? Why? I would ask again why this matters. I don't mean to be combative, I am as perplexed as you are. Maybe I am not as fazed by the odd choices of others.

Did you read through all of the posts in this thread? If not, then please do so. If you did, then please do so again.
By the way, he is not posting his personal preference. Still, did you read through all the posts in this thread?

The reason I want to limit the daytime slider is because, having it already going all the way to 2700K is just too much -- the words are difficult to line up, and 2700K is not a daytime color, it's more of a sunset color, as the sun is setting. The sun gets REALLY orange, and I would say it can get to 1900K just reflecting off of a white building.
For the daytime slider, I'd like it to be strecthed out more, so it's more consistent. Limiting it to 3400K would be great, because that's basically where it is on a fresh install until you expand the range.
Also I'd like to limit the night time slider, but that might cause a lot of issues with people, and that would really not be worth the trouble. Lots of people use the 4200K setting at night, and maybe a bit higher as well, so I guess lets just leave that alone for quite a while.
The current UI would not work this way -- the color gradient would be really confusing, so I'm hoping they set it up like it is currently on the mac version, it would work much better.

Well, I think it should be left the way it is, but with something added: an 'advanced' area or a 'custom' area where you get to choose any color you want at any time of the day or night.
I remember f.lux had 800K as an option. I'd like to see that again. I'd like to be able to choose anything from 800K all the way to 6500K in 1K increments. With the way that I live, I need that.
If Herf were to limit the 'Daytime' and 'At night' settings even further than they are now in any way, then we'd have more complaints about it and also more requests for it to be changed.

Thumbs up for the 800K. It will be epic. But I am not entirely sure it is possible.
At 1000K some of my icons of the screen go black :D
