Many Xiaomi smartphone users are faced with the need to change the color gamut of the display. Most often, the request for how to make a purple screen on a shaomi phone is associated with the desire to turn on the “Night Read” or “Paper Screen” mode. This feature, developed by the company’s engineers, is designed to reduce the load on the eyes in the dark, shifting the color temperature towards cold or specific shades. However, sometimes users notice the purple shade by accident, and then questions arise about the reasons for this color reproduction.
There are two main scenarios that we will look at in this article: One is the routine operation of software-based vision filters that are manually or automatically configured by the user on a schedule; the second scenario is the appearance of a purple spot or hue as a symptom of a hardware malfunction, such as polarizing film detachment or matrix overheating. Understanding the difference between software tuning and a physical defect is critical for future action.
In this guide, we will take a look at all the available ways to change color on MIUI and HyperOS devices. You will learn how to activate hidden functions, how to adjust automation and how to diagnose the state of the display. If you were looking for a way to make the screen purple for eye protection or just for visual effect, this information will be the most useful for you.
Activation of the reading mode and paper screen
The main tool that allows you to change the colors on the display of Xiaomi smartphone, is in the system settings of the screen. a feature known as “Read Mode” or “Paper Screen” can radically change the color palette of the interface. In some versions of the firmware when activated certain parameters, the background becomes yellowish, but when you add filters or in modes, it can take a purple or gray-blue hue.
To activate this feature, you need to go to the settings menu. The path may vary slightly depending on the version of the shell, but the logic remains the same. Find the partition responsible for the display and select the item related to vision protection. This is where the tools for fine-tuning color reproduction hide.
- 📱 Go to Settings and select Screen.
- 👁️ Find the Reading Mode or Vision Protection section.
- 🎨 Turn on the paper screen switch to change texture and color.
- 🌡️ Use Color Temperature to shift shades to the cold or warm side.
💡
Try turning on the paper screen mode and simultaneously twisting the color temperature towards the cold. In some Redmi models, this gives a pronounced purple-gray hue, mimicking electronic ink.
It's important to note that the intensity of the effect depends on the model of your device. On AMOLED-matrix, the change in color temperature can give a more noticeable result than on IPS-panels. If the standard settings do not give the desired purple hue, you can try to experiment with the color saturation slider in advanced settings.
Scheduling and automation
Manually turning on the purple screen can be uncomfortable if you want the device to switch to this mode automatically at a certain time.The MIUI system allows you to flexibly adjust the schedule of filters. This is especially true for those who use a smartphone to read before bed when bright light interferes with the production of melatonin.
You can set a specific time to turn on and off the function, such as setting up automatic start at 20:00 and shutdown at 07:00, in which case your phone will switch to the mode with the changed color reproduction, which eliminates the need to search for settings manually every evening.
☑️ Automatic setting
There is also the option “Adaptive Mode”: When it is turned on, the smartphone analyzes the ambient light using the sensor and adjusts the brightness and color temperature on its own, and adapting to the surroundings can make the screen appear colder or take on a specific shade.
Remember that some third-party book-reading apps have their own built-in filters. If you use such programs, their settings may overlap with Xiaomi’s system settings, in which case the purple screen will only appear inside a particular application.
Use of digital balance and filters
Modern versions of Android, which are the basis of the Xiaomi shell, have implemented digital well-being features, which include “Sleep” or “Sleep Time” mode, which also affects the display of colors. Although the main purpose of this mode is to make the screen black and white, in combination with night mode, it can produce interesting visual effects.
To find these settings, go to the digital balance section, where you can activate grayscale mode. If you turn on a blue light filter at the same time, the final image may be perceived by the eye as having a purple tide, and this is due to the mixing of color channels.
| Function | Location on the menu | Effect on color | Purpose of use |
|---|---|---|---|
| Night mode. | Screen. → Protection of vision | Warm yellow/orange | Reduction of the blue spectrum |
| Paper screen | Screen → Reading mode | Gray/Textured | Imitation of paper |
| Digital balance | Digital balance → Sleep regimen | Black and white. | Reducing dependence |
| Dark subject matter | Wallpaper and personalization | Black background/Bright text | Saving energy |
Experimenting with a combination of these features can achieve almost any shade, for example, incorporating a dark theme in combination with reading mode and shifting the color temperature to the cold side often produces the deep purple-black color that many users are looking for.
Diagnostics of hardware problems with the display
Unfortunately, the “how to make a purple screen” request often comes not from a desire to customize the gadget, but from the sudden appearance of a defect.If your Xiaomi has a purple stain, a stripe or the entire screen has gone into a purple hue without your actions, this is an alarm.
The most common cause of purple spots on AMOLED-Xiaomi screens are a detachment of the organic layer or damage to the polarization film, which can occur after a fall, strong pressure or simply because of the aging of the matrix. Unlike software settings, this defect does not disappear when you reboot.
⚠️ Attention: If the purple spot on the screen gradually grows or changes shape, this is a sign of degradation of organic LEDs.
Also, purple can indicate problems with the plume of the display. If the plume has moved or oxidized, the transmission of color signals is disrupted, in which case the screen can flash, ripple or display incorrect colors only in certain areas.
- 🔍 Look at the screen when the lights are off – the glow may indicate damage.
- 🖐️ Carefully press the corners of the screen (no bigotry) – if the color changes, the problem is the contact of the plume.
- 📉 Check if the phone is overheating – high temperature accelerates the degradation of the matrix.
- 💧 Make sure there is no moisture – water intrusion often causes contact oxidation and color change.
Hidden engineering codes and calibration
For advanced users, there's an engineering menu that can check the color channels of the matrix, not a way to make the screen purple all the time, but a great diagnostic tool, and test patterns can tell if the display is working or if the software is having a problem.
To get to the engineering menu, use the standard code ##6484##. From the menu that opens, select the item associated with the display (usually called Display or Color), where you can run tests for displaying red, green, blue and white.
##6484## -> Display Test -> Color BarIf you see clear purple lights on a white background during the test, which are not in normal use mode, this confirms a hardware problem. If the test colors are displayed perfectly clean, then the purple shade in the system is caused by software filters or theme settings.
What to do if the test shows a defect?
Impact of Design Themes and Third-Party Applications
Personalization is a must. MIUI allows you to set themes that completely change the visual style of the system. Some theme writers create designs that are dominated by purple tones, deep shadows and specific status bar designs, in which case the purple screen is just a feature of the style you choose.
Check out the Themes app. If you have a third-party theme installed, try switching to a standard one. Wallpaper can also have an impact. Dark wallpaper with purple gradients combined with translucent interface elements create the illusion of changing the color of the entire screen.
And then there are filter apps from Google Play that put a color layer over all the windows, and they're often used to create (the atmosphere) or to reduce eye fatigue in a non-standard way, and if you've installed these tools, they can be the reason for the color rendering changes.
⚠️ Warning: When installing third-party apps to change the colors of the screen, carefully read permissions. They require access to the display over other windows, which can theoretically be used for phishing or displaying ads.
Removing suspicious apps and returning to a standard theme is a quick way to check if they are the cause of the purpleness, and if the screen is normal after doing so, the problem is solved by software.
💡
In 90% of cases, the purple shade on Xiaomi is either an on-line vision protection mode or a defect. AMOLED-Matrices: Software viruses that change the color of the screen are extremely rare.
