Modern. OLED-The displays installed in the current Xiaomi, Redmi and Poco smartphones are capable of transmitting millions of shades, but the factory calibration does not always correspond to the individual preferences of the user. Some people find the screen too cold with a bluish tint, while others lack the juiciness of the colors when viewing photos or videos. Often there is a need to change the color reproduction to reduce the load on the eyes or just for aesthetic pleasure.
With MIUI and the new HyperOS, developers have developed flexible visual content management tools, so you can not only switch the color scheme to the inverted color scheme for night reading, but also fine-tune the saturation of each primary color separately, allowing you to tailor the image to personal tastes or specific tasks, such as retouching photos.
However, before making changes to system parameters, it is important to understand the difference between software correction and the hardware capabilities of the matrix. Changing the color profile is a software manipulation that reassigns the values of the pixels, but can not physically change the characteristics of the LEDs.
Using the Color Inversion Mode
The most radical way to change color reproduction is to activate the inversion mode, in which case black becomes white and white becomes black, the other shades also change to the opposite, a feature originally designed for people with visual impairments, but can also be useful for reducing the brightness of the screen in complete darkness when the standard minimum of backlight is not enough.
To activate this feature, you need to go to the settings menu and find the section responsible for additional system parameters. The path may vary slightly depending on the firmware version, but the logic remains the same. Once turned on, the interface will resemble a negative, which at first can be disorienting, but after a few minutes of use, the eyes become accustomed.
It's important to note that when you turn on the inversion, some images can look unnatural and the video can turn on strange shades. This is normal behavior of the system, because the entire output signal is inverted. If you use your phone to work with graphics, it's better to turn off this mode.
- 🔄 Go to Settings. → Additional settings to find the desired item.
- 👁️ Find the Special Opportunities or Accessibility section at the bottom of the list.
- 🎨 Select Color Inversion and activate the slider.
- 💡 Use a volume button combination for a quick call if the hot key is set up.
⚠️ Attention: Inversion mode can distort colors in games and applications, making the interface difficult to read.
Setting up color profiles and saturation
A more subtle tool is the choice of color profile. Xiaomi smartphones often have a Vivid profile installed by default, which twists colors to maximum to create a wow effect on the storefront. If you like a more realistic, "standard" picture, like on sRGB monitors, the profile should be switched.
The display menu has a color scheme feature, where you can choose one of the preset options or go to advanced settings, and in the extended mode you can manually move sliders for red, green and blue channels, achieving the perfect white balance.
When you manually adjust, try not to go to extremes. Excessive saturation of one channel will lead to colored halos around text and objects. The best solution is to reset all sliders to zero and only slightly correct when clearly necessary.
What is a gamma correction?

Color temperature adjustment
Color temperature is measured in Kelvins and determines the shade of white on the screen. Low values (about 4000-5000K) give a warm, yellowish light that tires the eyes less at night. High values (7000-9000K) create a cold, bluish glow that is invigorating but can interfere with the production of melatonin before bedtime.
Xiaomi's screen settings have a separate slider to adjust this setting, and by moving it, you can make the screen warmer or cooler, regardless of the color profile you choose, and this is one of the most effective ways to personalize your device.
Many users mistakenly believe that warm light is bad for the eyes. In fact, it is the blue spectrum that prevails in cold colors that causes the most stress during long-term reading, so it is recommended to shift the slider to the right, towards warm shades, for reading books and news.
💡
For evening use, move the color temperature slider to the right until a light yellow tint appears - this will reduce the load on the retina and help you fall asleep faster.
- 🌡️ In the screen menu, find the Color Temperature section.
- 👈 Move the slider to the left for cold hues (blue spectrum).
- 👉 Move the slider to the right for warm hues (yellow spectrum).
- 👀 Focus on the white background in the browser when setting up.
Vision protection and night mode
Special attention should be paid to software filters such as Reading Mode and Night Mode, which, unlike simple temperature control, use a complex blue light filtering algorithm to make the image softer and more electronic paper-like.
New versions of HyperOS include Vision Protection 2.0, which dynamically changes the color spectrum depending on the time of day and the lighting environment, and decides when to warm the screen and when to return the natural colors.
Activating these modes can cause the colors to fade and unsaturated. That's the price of eye comfort. It's a great solution for watching videos in the dark, but for photo work, it's best to turn off these filters so you don't distort the perception of colors.
| Regime. | Impact on colours | Recommended time | Impact on the battery |
|---|---|---|---|
| Standard. | Natural colors | Day | Normal. |
| Saturated | Bright, juicy tones | Multimedia. | Normal. |
| Protection of vision | Warm, yellowish | Evening/Night | Reduced |
| Paper | Monochrome shades | Reading text | Minimum |
⚠️ Warning: Turning on the "Paper" mode puts the screen in black and white, making it impossible to view color photos and videos in the original form.
Advanced settings through the engineering menu
For advanced users, there is a possibility to access hidden display settings through engineering menus or special commands, but in modern versions of MIUI, access to these features is severely limited for security reasons, changing the parameters here can lead to incorrect touch screen operation or the appearance of artifacts.
If standard settings aren't enough, you can use third-party apps from Google Play that overlay a color filter on top of the interface, which work by dimming or overlaying a layer of a certain color without changing the system settings.
Using these applications requires special permissions to "mask over other windows." Be careful: poor-quality filters can cause micro-interface delays or increased battery consumption due to constant redrawing of layers.
☑️ Checking the display settings
- 🛠️ Use only proven color correction apps.
- 📉 Watch for heating of the device when using heavy filters.
- 🔒 Do not try to change the settings in the engineering menu without a backup.
- 📱 Remember that third-party filters may conflict with dark topics.
Impact OLED-color-transfer technology
Understanding screen technology helps to better customize the device. Xiaomi mid-range and flagship smartphones use AMOLED and OLED arrays. The peculiarity is that each pixel glows independently, which allows you to achieve the perfect black color by simply turning off the corresponding pixels.
But there's a feature about these screens: at low brightness, some arrays can use pulse-width modulation (PWM) to adjust the glow, which can cause flickering that some users perceive as color change or ripples. The screen settings often have an "anti-PWM" or "Tickle-Eliminate" option that changes how the backlight works.
Turning on PWM frequency can slightly change the color gamut in dark colors, making them a little more gray, but it reduces the strain on the eyes. It is a compromise between the quality of color reproduction in the dark and comfort of use.
💡
OLED technology allows you to save charge when using dark themes design, as the black pixels in them are completely turned off.
It is also worth considering that OLED-The constant use of maximum saturation and brightness values can accelerate this process, which over time will lead to a change in the color balance of the entire screen (the appearance of a pink or greenish shade).
Why do colors go down after the firmware update?
Can I return the standard colors after setting up?
Does the screen protector affect the color of the screen?
Why are the colors different on Xiaomi phones?
⚠️ Note: If you notice a sharp change in screen color (green or pink spots) that is not eliminated by settings, this may indicate a physical malfunction of the matrix or plume.
To sum up, changing the color of the screen on Xiaomi is a process of fine-tuning yourself. From simple profiles to manual temperature calibration, you can make your smartphone as comfortable as possible. The main thing is not to be afraid to experiment with sliders to find the balance that will suit your eyes.
