Smartphones of the Redmi 8 series are equipped with high-quality IPS-The screens are designed to be comfortable by default, but many users are faced with a situation where the screen takes on an unnatural yellowish tint, even in the daytime. This phenomenon is often confused with the breakdown of the matrix, although in fact we are talking about software filters designed to protect vision.
The MIUI system on the device offers flexible color management tools, the problem is that the eye protection function is often activated automatically or by the owner's carelessness, resulting in fading and distorted colors, which interferes with normal photo or video processing.
In this article, we will discuss all possible causes of the night effect on the screen, you will learn how to force the blue light filter to turn off, adjust the color scheme to your preferences and return the display to its natural brightness. The instructions are relevant for all modifications of Xiaomi Redmi 8 and Redmi 8A.
Causes of the appearance of a yellow tint on the display
Before you start setting up, you need to understand the nature of the unwanted effect. The main reason is the Eye Protection function, which filters the short-wavelength blue spectrum of the screen radiation, and it is believed that blue light disrupts the production of melatonin, so the screen automatically gets warmer in the evening.
The second factor is the activated Reading Mode, which, unlike a simple filter, mimics the look of the e-paper, removing the color saturation and adding a distinctive texture, so if you accidentally switched to this mode, the screen will look like a page of an old book.
Automatic brightness and light sensors can also be considered, and algorithms can misinterpret ambient lighting, believing you're in a dark room, and darken the screen by adding warm colors. Sometimes the problem lies in third-party launchers or design themes that force the color gamut of the interface.
Turning off reading and eye protection
The fastest way to get back to normal colors is to check the basic display settings, which are all in the same menu but work independently in the MIUI shell, and you need to go to the screen settings section where all the image management tools are concentrated.
Find Settings → Screen → Eye Protection. Here you will see a switch that activates or deactivates the filter. If the slider is on blue, then the mode is active. Turn it off to remove the yellowness. Below is an intensity slider that allows you to adjust the filtration force manually if you don't like a full shutdown.
Separately, check the read mode. It can be turned on even when the eye protection is turned off. Go to Settings → Screen → Read mode. Make sure that the Read mode switch is in the Off position. In the same menu, you can configure applications for which the mode is turned on automatically, eliminating unnecessary programs from the list.
☑️ Checking screen settings
It's important to note that the changes take effect instantly, and if the screen is yellow after doing these actions, it may be that the problem lies deeper in the system settings or activation schedule.
Scheduling and automation
Users often complain that the mode turns on on itself at a certain time, which is the work of an automatic schedule that can be set by default to the period from dusk to dawn, and the system uses geolocation to determine the time of dusk, which sometimes leads to errors.
To control this process, go back to the Eye Protection menu. Find the Schedule. There are three options available: Off, On and Scheduled. If you choose the third option, the phone will ignore your manual attempts to turn off the filter at a given time.
To fully control the situation, it is recommended to set off mode or set your own time, for example, you can set the filter on only from 23:00 to 07:00, this will avoid sudden changes in colors during the day when you work with graphics or watch videos.
⚠️ Warning: Automatic switching may conflict with wake alarms. If your phone changes colors dramatically when you first wake up, check your schedule settings first.
You also need to look at Adaptive Brightness, which is related to color temperature in some firmware versions, and try turning off autobrightness manually and putting the slider at a comfortable level to eliminate the effect of the light sensor on color reproduction.

Calibration of color scheme and saturation
If the filters are turned off and the colors still seem unnatural, the color scheme may have been knocked down.The Xiaomi Redmi 8 lets you choose between multiple display profiles, each of which interprets colors differently.
Settings → Screen → Color Scheme (or Color Mode) offers options: Standard, Saturated, Contrast and Classic. The default is often Standard or Saturated, which can give you excessive heat. Try switching to Classic or sRGB to get the most accurate color reproduction close to reality.
For advanced users, manual calibration is available, and you can find the settings of the individual channels in the same menu: red, green and blue; you can neutralize any shade by moving the sliders, but you should be careful not to get acid colors.
Below is a table describing the effect of different modes on image perception:
| Regime. | Description | Impact on colours | Recommended use |
|---|---|---|---|
| Standard. | Balance between brightness and naturalness | A little warm white. | Everyday use |
| Saturated | Enhancing contrast and depth | Bright, sometimes oversaturated colors | Watching videos, playing games |
| Classical. | Standard sRGB | Maximum precision, cold gamma | Photos, documents |
| Contrast | Increase the difference between light and dark | Deep black, sharp transitions | Reading text in dim light |
💡
To calibrate white, use a white background app (such as notes) and compare a screen with a blank piece of paper in daylight and adjust the diagram so that white appears white instead of yellow or blue.
Use of third-party applications and themes
Remember that color reproduction can be influenced by the themes set up in MIUI Themes. Some designers change the system colors to make the interface more "lamp" or, conversely, acidic. If the problem arose after the theme change, try to return the standard design.
And then there are third-party eye protection apps like Twilight or Blue Light Filter, which run on top of system settings and can have their own schedules, check the list of installed apps for these utilities, if they are found, delete them or disable them in the settings of the app itself.
In rare cases, color distortion is caused by widgets or launchers. If you use a third-party desktop, check its theme settings. Sometimes resetting the launcher to factory settings helps eliminate visual bugs without affecting user personal data.
⚠️ Warning: Third-party filters may conflict with system filters. If you use an eye protection app, be sure to turn off the built-in Eye Protection in Xiaomi's settings, otherwise the colors can become unpredictable.
Also check if Color Inversion mode is enabled for visually impaired people, which is located in Settings → Advanced Settings → Special Features → Visual. Activating this feature makes the image negative, which often scares inexperienced users.
Resetting settings and eliminating software failures
If none of the above methods worked, there may have been a software failure, and the display settings may have been damaged after a failed update or installation of incorrect software, in which case a reset of the screen settings or a complete reset of the device will help.
Try resetting only the screen settings first. Go to Settings → Screen and look for the reset button (not all versions of MIUI have one). If you don't have one, you can use Safe Mode. To do this, press the off button, and then hold your finger on the "off" button on the screen for a long time until you get a suggestion to go to Safe Mode.
In Safe Mode, only system applications are loaded, and if the screen is normally displayed in this mode, then the problem is in one of the apps you have installed, and remove the newly installed programs one by one until the problem disappears.
💡
If the yellow tint is maintained in safe mode, this indicates a hardware problem or a deep firmware system failure requiring the device to be flashed.
The last resort is a full reset to factory settings (Wipe & Reset).Be sure to back up all important data before you do so, as it will be deleted.This step is guaranteed to return all settings, including display settings, to factory status.
