Modern Xiaomi smartphones are famous for their high-quality displays, but sometimes users face the need to change the color gamut of the screen. Often the phrase “how to switch tone mode” device owners mean adjusting color temperature, turning on reading mode or eliminating incorrect display of shades. Deep adjustment of the visual interface allows you to adapt the gadget to individual preferences of vision or specific tasks that require accurate color reproduction.
MIUI has many hidden features for screen calibration that are not always obvious at first glance, and a change in tone may be necessary if the screen is green or yellow, or if you want to reduce eye strain at night.
The concept of tone mode in the MIUI ecosystem
The term “tone mode” is not the official name of a separate feature on the Xiaomi menu, but rather a collective term describing the color state of the display. Depending on the device model and the version of the shell, color management is carried out through the parameters of Color Scheme or Reading Mode. Understanding the difference between these functions is the first step to competent tuning.
Standard settings allow you to switch between rich, standard and improved colors. However, fine work with shades often requires access to an engineering menu or use third-party applications. Resetting color settings to factory values often solves 80% of the problems with the incorrect "tone" of the screen. It is important to distinguish between software failure of colors and physical degradation of the matrix.
If your smartphone suddenly changes to unnatural colors, it may be due to a firmware update or a malfunction of the display drivers. In such cases, manual adjustment through the system sliders helps to return the usual picture.
Why can colors be distorted?
Basic setting of the color scheme of the screen
The first and most affordable way to change the tone of an image is in the standard settings menu, where the user can choose the one that is best suited for his perception. To access these parameters, go to Settings → Screen → Colors and saturation.
The menu that opens usually has multiple profiles: "Standard", "Saturated", "Enhanced" and "Contrast". The "Standard" profile selection often returns colors to factory values, eliminating excessive brightness or fading. If you want a warmer gamut, you should experiment with the "Improved" profile, which often adds yellowness to simulate paper.
- 🎨 Standard: Basic calibration close to sRGB is suitable for most tasks.
- 🌈 Saturated: Increases the brightness of colors, making the picture more “juicy”, but less realistic.
- 👁️ Improved: Optimizes colors to reduce eye strain by adding warm tones.
- ⚖️ Contrast: Increases the difference between light and dark, which can visually change the perception of tones.
💡
Use live wallpaper with gradients when adjusting colors - on a static monotonous background, it is more difficult to assess the uniformity of the distribution of shades throughout the matrix area.
Use of reading and night lighting mode
If you mean "tone mode" to turn the screen into shades of gray or sepia for comfortable reading, you'll need vision protection functions. In MIUI, Read Mode and Sun Mode are responsible for this, and activating these functions dramatically changes the tone of the image, removing the blue spectrum.
To enable, go to Settings → Screen. → Reading mode: You can choose between "Classic" (shades of gray) and "Text" (sepia) and it's the perfect way to put your phone in monochrome tone mode, which is especially true for people with high eye sensitivity or to save battery life. AMOLED-screen.
One of the things that we should mention is the Night Light feature, which automatically warms the screen in the evening, and the flexible schedule allows the phone to go into "warm" mode after sunset, which not only changes the tone, but also helps produce melatonin, improving sleep quality.
☑️ Setting up the reading mode
Manual calibration through the engineering menu
For advanced users who lack standard settings, manual calibration is possible through an engineering menu, a powerful tool that allows you to influence individual color channels (Red, Green, Blue), accessed through hidden code in the Phone application.
You need to dial ##6484## or ##3646633## (code may vary depending on the processor: MediaTek or Snapdragon). Once in the CIT menu, you should find the section associated with the display, often called Display or LCD. There may be sliders available to correct white balance.
⚠️ Note: Making changes to the engineering menu without understanding the principles of color channels can lead to complete inability to use the screen properly!
Changes in the engineering menu are permanent and persist even after you reboot. If you accidentally hit the settings and don't remember the original numbers, the only way out is to completely reset the device or flash it over. Be extremely careful when adjusting the Gains settings for each color.
Comparison of methods of shade correction
The choice of the method of setting depends on the ultimate goal: whether you just want to make the screen warmer, remove the green shade or move the device to monochrome. Below is a table that helps determine the appropriate way to solve your problem.
| Method | Difficulty | Impact on the system | Purpose of use |
|---|---|---|---|
| Standard profiles | Low. | Safe. | General correction of color reproduction |
| Reading mode | Low. | Safe. | Reading, battery saving, monochrome |
| Engineering menu | Tall. | Risk of failure | Accurate calibration, elimination of defects |
| Third-party annexes | Medium | Demands a license. | Flexible configuration without root rights (partially) |
| Developer settings | Medium | Safe. | Simulation of color blindness, inversion |
💡
For most users, standard color profiles and reading modes are sufficient, and only use the engineering menu as a last resort if you have technical knowledge.
Resolving color reproduction problems
Sometimes users are looking for a way to turn the phone tone because the screen has spontaneously turned yellow, blue or pink, a phenomenon often referred to as the "green" or "yellow" matrix, and if standard settings don't help bring the color back to normal, the problem may be deeper.
One of the common reasons is activation of the function "Memory Extension" or overheating of the device, which affects the operation of the display controller. It is also worth checking whether special features are included for people with visual impairments. Go to Settings → Advanced Settings → Special features and make sure that the "Color Inversion" or "Color Correction" items are turned off.
If the software methods are powerless and the shades on the screen remain unnatural (for example, white frankly goes green or pink), there is a high probability of hardware malfunction. This can be a sign of detachment of the plume or degradation of organic LEDs in AMOLED-matrixes, in which case the software "translation" into another mode will not save the situation.
⚠️ Warning: If you see pink or green spots on the screen that don't disappear after you reboot, it's a sign of physical damage to the matrix.
