Modern OLED-matrixes in smartphones Xiaomi and Redmi often have oversaturated colors by default, which can tire the eyes or distort the real shades in photos. Users who are first encountering the shell of MIUI or HyperOS, often wonder how to bring the image to a more natural look or, conversely, make it as bright as possible for games.Tunes the color range is not just a matter of aesthetics, but also a way to reduce the load on vision with prolonged use of the gadget.
In this article, we will take a look at all the color management tools available, from basic profiles to advanced calibration through the engineering menu. You will learn how to turn on reading mode, adjust a dark theme for specific applications, and what to do if the screen is unexpectedly greenish or yellow. Understanding these settings will allow you to unlock the potential of your display to the maximum.
Basic color reproduction profiles in screen settings
The first place to look at when you want to change the look of the interface is the standard settings menu. In current firmware versions, the path usually looks like Settings → Screen → Color scheme. Here, the system offers several preset modes, each of which changes the image processing algorithm.
Vivid is the default mode on most models, and it enforces color gamut to make red and green shades more aggressive. This may be something you like when watching videos, but it's often not the right option for graphics or reading text. Switching to Standard or Classic mode brings colors back to the sRGB gamut, making the picture paler but realistic.
⚠️ Note: After selecting a new profile, colors may not change immediately in all applications. Some programs cache color profiles, so you may need to fully restart your smartphone to apply the changes.
Owners of the flagship Xiaomi 13 or Xiaomi 14 models may notice additional settings, such as “Master of Color” or Dolby Vision support. These features automatically adjust brightness and contrast depending on the content on the screen. If your goal is maximum color accuracy, it is recommended to turn off all “improvers” and leave only the basic calibration.
Fine tuning of shades and temperature correction
For those who lack standard profiles, the system offers deeper tools. In the Settings section → Screen → Color scheme, there is often a "Color Temperature" slider or the option to select a white point. By moving this slider, you shift the white balance towards cold (blue) or warm (yellow) tones.
Cold spectrum usually makes the image sharper and contrasting, which is clearly visible during the day in bright sun. However, the blue light emitted by the matrix in this mode can suppress the production of melatonin, which negatively affects sleep. Warm spectrum mimics the colors of electronic paper, reducing the strain on the eyes in the evening.
And you should pay special attention to DC Dimming, if it's available in your area, and although it doesn't directly change colors, it affects the perception of brightness at low backlight levels by removing flicker, and you can find it by activating a hidden menu through a set of code in your phone or in the "Developers" section.
💡
Use Paper Mode to read books, which puts the screen in a monochrome yellowish mode, which saves battery life and saves your eyesight.
Use Eye Comfort and Schedule
Eye Comfort is critical to eye health, filtering some of the blue spectrum to make the image warmer, and unlike just changing the temperature, it works at the driver level, providing more effective protection.
The most convenient way to use it is to set a schedule. The system can automatically turn on the warm filter at sunset and turn it off at dawn using geolocation data. To do this, go to Settings → Screen → Vision Protection → Schedule and select "Downset to Dawn".
There's also an Ultra or Paper mode that turns the screen into an e-book, which allows you to adjust the texture of the background and contrast levels of text, and is ideal for long-term document work or reading news in the dark.
| Regime. | Impact on colours | Recommended time | Impact on the battery |
|---|---|---|---|
| Saturated | Bright, oversaturated colors | Daytime, games, media | Standard. |
| Standard. | Natural shades of sRGB | Work, photo | Standard. |
| Protection of vision | Warm, yellowish hue | Evening, night | Minor savings |
| Paperwork | Black and white, low contrast | Reading books | High savings |
☑️ Setting up night mode
Dark Theme and Its Influence on Color Perception
The inclusion of Dark Mode dramatically changes the perception of the interface's color scheme. OLED-smartphone screen POCO Redmi is not just a color inversion, but a black subpixel that saves energy.
MIUI and HyperOS have Adaptive Dark Mode, which allows you to force dark theme to be included even for applications that don’t have that option, and it’s on the Settings path → Screen → Dark Mode → Adaptation for individual applications.
It is worth noting that when you activate a dark theme, the system can automatically adjust the brightness and contrast of the icons so that they do not “cut” the eyes against a black background. If you notice that the colors have become dull, try changing the wallpaper to darker ones - the system algorithms often adjust the color scheme of the widgets to the background of the desktop.
⚠️ Note: Some firmware versions may reset user color calibration when Dark Theme is turned on. If the colors become unnatural after Dark Mode is turned on, recheck the profile in the Color Scheme section".
Calibration through the engineering menu and third-party utilities
For advanced users wanting to achieve perfect color rendering, there are hidden tools. - Engineering menu CIT It allows you to test the display, but to change the color constants (RGB Gain) root rights are often required or ADB-Be careful: a misalignment of the values in the engineering menu can lead to incorrect screen operation.
A safer way to do this is to use Google Play calibration apps like TestUFO or Display Calibration, which help you visually identify a skew toward one of the colors and match your profile in standard settings. ADB to disable hardware color acceleration if the system is not properly processing HDR-content:
adb shell settings put global peak_refresh_rate 60This command limits refresh rates, which in some cases helps stabilize color drivers on older models. However, the main tool is still software calibration through system settings. If the screen has a clear factory defect (for example, green stripe or burnout), software methods will not help - you will need to replace the module.
What is DC Dimming and How to Include It?
Solving problems with incorrect display of colors
Sometimes users are faced with a situation where the settings are downed and the screen shows unnatural colors, this can be due to a system failure, a firmware update or physical damage to the matrix. The first step should always be to reset the color settings to factory values in the corresponding menu.
If the software reset doesn’t help, it’s worth checking if Monochrome mode is included in special features. Settings path → Advanced settings → Special features → Visual can hide the activated Color Correction or Color Inversion mode, which globally changes the scheme.
In the case where the problem only manifests itself in certain applications (for example, YouTube yellows, but the browser works fine), it is about HDR settings or energy saving. Try turning off battery optimization for the problematic application or resetting Google Play Services.
💡
If the screen has a uniform greenish or pinkish tint on a white background even after resetting, this is most likely a sign of degradation. OLED-matrices or plume detachment, which requires repair in the service center.
