Night mode in Android. What is iPhone color inversion and what is it for? Invert colors on your phone

Sometimes even the minimum display brightness is excessive for reading in the dark. The screen still continues to dazzle and greatly tires the eyes. Read below to learn how to set up the so-called night mode for reading, browsing websites, or working with other applications at night.

In some modified builds of Android, as well as Blackberry and iOS, there is a so-called inverted mode, which, as the name suggests, inverts the colors to the opposite ones, or in other words, creates a negative image.

If we assume that text on websites and in general is usually placed on a light background, then inverting, in principle, should work like a night mode. The problem with this mode becomes obvious when it also inverts the dark color to white and therefore creates new bright areas on the screen that interfere with the use of the device in the dark.

Inverted mode usually inverts images, which is why they often change beyond recognition.

Ideal night mode

Ideally, night mode should invert only light tones into dark ones, leaving only text on the page as white, while ignoring pictures, and muting them if possible (perhaps even converting them into monotone images).

In practice, we have both the complete absence of such a mode in most versions of Android, and its incorrect implementation, when instead of smart inversion, a regular “negative” is used.

Of course, for various types of activities (reading, browsing, etc.) you can individually select applications that have a night mode, but this takes a long time, is not always possible, and does not solve problems with the interface of Android itself, which will blind your eyes when minimizing applications.

This is what the desktop looks like after enabling inverted mode. Too bright for the dark.

Screen Filter - reduces brightness below the minimum system level

Before using true night mode, you can try simpler options, such as further reducing the screen brightness.

Using Screen Filter, the brightness can be reduced to values ​​much lower than what the system allows. Moreover, somewhere at values ​​of 10% and below, the brightness becomes so low that nothing can be distinguished on the screen even in complete darkness.

Protection against inaccurate brightness reduction is almost the same as when changing the resolution on video cards. If you do not confirm the selected value after 10 seconds, the brightness will be reset to the previous value.

At values ​​of approximately 40%, Screen Filter makes it much easier to work with the tablet in a dark room.

But at lower values, problems with contrast may already arise. The brightness of the screen continues to decrease, but with it the text stands out against the general background, which makes it more difficult to read.

Another advantage of Screen Filter is its convenient controls. One click on the icon and the brightness decreases, another click returns to the system value. Settings are configured in the notification panel.

As a bonus, lowering the brightness also results in increased battery life. True, different screens react differently to changing this parameter. Apparently, devices with Amoled screens will benefit the most in this regard.

CF.lumen - night mode and invert colors

CF.lumen requires root to run and is one of the few programs that allows you to enable inverted mode on Android at the system level.

By default, the program uses an automatic mode for adjusting screen color (not only brightness, but also warmth) depending on the time of day. To do this, the program needs to set the device location. We don't need automatic mode, but we still have to specify the coordinates. To do this, you need to turn on GPS, wait for the coordinates to be automatically determined, or indicate them manually on the World map.

After this, you can go to the Master filter mode section, in which the color inversion mode is available. However, as the test showed, it is not the most convenient for reading, for the reasons already listed above: inverting pictures and black tones.

Here's what it looks like in practice. The bottom and top panels may not immediately catch your eye, but they are white and shine very strongly in the dark.

As it turned out, for working with the device in the dark, the so-called “red” mode is perceived much better by the eyes. In this mode, a red layer is superimposed on top of the image, which, together with the reduced brightness, is perceived by the eyes better than all other modes I have tested.

Perhaps the abundance of red in the screenshot causes rejection, and when viewing the picture you yourself have similar feelings, but in the dark it is in this mode that it is much more pleasant to look at the screen: your eyes don’t hurt from bright light, you don’t have to squint, the text is perceived well, rather than low-contrast.

Red light is often used for illumination at night in cases where night vision is needed. This explains its mild effect on the eyes.

CF.lumen has the ability to adjust the brightness parameter, but not lower than the system values, so it is advisable to use the program simultaneously with Screen Filter. Perhaps not the most convenient option (although running two programs is not at all difficult), however, another equally correct and universal night mode for Android apparently does not exist yet.

CF.lumen + Screen Filter in action. You can look at such a picture in almost complete darkness from a normal angle without covering your eyes.

The CF.lumen application installs its own driver for color correction and the developer warns that it is strongly recommended to remove the driver when updating the system. A similar program in the Play Market, which also requires root rights, warns that the device may not boot and will have to be reset. CF.lumen seems to be safer in this regard, but do not use the program if you do not know what it is about.

Among the others, the smart invert function is currently the closest to creating the Dark Mode effect on the iPhone, iPad and iPod. This is a new feature on and above, it allows the operating system to change the colors of the interface, maintaining the standard look and color of content such as your photos, App Store design, etc.

Smart Inversion is smart enough to not change the color of your wallpaper. However, the color of the dock, the status of the bar and other parts of the interface will change.

iOS will try its best to identify content whose color doesn't need to be changed, but don't expect miracles.

Smart Invert will change the colors of web pages in Safari, along with all images and text, just like album covers in the music app. And it doesn't look very good.

On the other hand, this mod will perform much better in Settings, Messages and other standard applications. In the Watch and Activity apps, the smart inversion feature will leave their already dark interface.

Before we begin, it's worth noting again that the smart version requires or higher.

On older iOS, only the classic mod is available, which inverts the colors of the entire display for visually impaired users.

How to invert colors on stock Android

If you are using a stock Android device, then inverting the colors is very simple.

Pull down the notification bar first, and then pull it down again. Find the option called "Reverse Colors". If it doesn't appear on the first page of Quick Settings, you may need to scroll through the pages.

If for some reason the setting is still not visible, you can easily add this tile. Click the little pencil icon at the bottom (this will allow you to edit the Quick Settings panel), find the Reverse Colors tile and drag it to the top area. Likewise, if this tile appears on the second page and you want it to be on the first quick access page, then you can move it to the main page. If you place it in the top six places, it will appear in the permanent settings panel, so you won't have to pull down the notification panel a second time. It's all about convenience.

Owners of smartphones based on the Android and iOS operating systems have been waiting for a long time for Google and Apple to deign to add a dark theme to the operating system, which would allow them to comfortably use their mobile device in the evening and at night. In fact, all Android smartphones already have a setting hidden from prying eyes that allows you to enable a dark theme, but many people just don’t even know about it.

The good thing about a dark design theme is that it significantly reduces eye strain at night and in the evening, when there are no light sources indoors or outdoors. If you read black text on a bright white screen for a long time, your eyes will begin to experience greater strain, which can subsequently lead to vision problems. To avoid this, you need to use a dark theme, which makes the background black and the font white.

Enabling dark theme on all Android smartphones is very easy and requires just a few simple steps. You can use this color scheme on absolutely all mobile devices and tablets running the Android 5.0 Lollipop operating system and later. Google notes that this can lead to a large reduction in speed (up to 5%).

To activate the night theme, you should launch “Settings”, and then go to the “Advanced” section, in which you should select “Accessibility”. At the very bottom of this section, you should activate the toggle switch opposite “Invert colors”, as a result of which the entire interface of the Android operating system will become dark. Most of the elements will look as if they were designed for this type of display, but there are some disadvantages.

The main disadvantage is that all icons and images will also be displayed with inverted colors, that is, they will look extremely unusual to the human eye. However, the dark theme on Android can be enabled whenever you plan to use mobile devices for a long time in the evening and at night. I would like to believe that in the future Google will add a full-fledged and native night mode to the Android operating system, which will allow you to use smartphones and tablets with greater comfort.
