How to change the color of letters to Xiaomi: the complete guide

Xiaomi, Redmi and Poco smartphone owners often aim to personalize their device by making it look unique. One of the most visible interface elements is the system font that is displayed in menus, contacts and messages. The standard MIUI or HyperOS shell offers basic settings, but a deeper approach is required to fully change the color gamut of text.

Many users are wondering why you can't just choose a color in standard screen settings, because the system font is a graphic file that contains information about the shape and color of the characters, and changing the color of the letters is essentially replacing one font file with another, specially modified or created by a designer.

In this article, we will discuss all the available ways to transform the text interface of your gadget, learn how to safely implement new styles, where to find quality resources and what risks can arise when modifying system files. Changing system fonts does not require root rights if you use official tools of the store.

Features of the fonts in MIUI and HyperOS

Xiaomi's shell has its own graphics display architecture. Unlike pure Android, it's very closely integrated with the theme. When you change the theme, the font often changes, but the text color can stay black or white depending on the interface palette you choose.

For letters to become colored (e.g. red, blue or gradient), you need to use special.mtz or.ttf files with embedded color tables. Common fonts downloaded from the Internet often contain only information about the shape of the glyphs, but not about their color.

⚠️ Note: Using fonts from unverified sources can lead to "squares" instead of letters or the complete disappearance of text in the menu. Always back up before installing.

There are two main ways to do this: using the built-in Themes app and manually installing it through a file manager. The first is safer and easier for beginners, the second gives more freedom but requires caution. System restrictions can block the installation of some modified files unless they are signed with a developer digital certificate.

💡

Before installing any new font, make sure that the battery is over 50% to avoid any disruptions in the application process.

Change the font through the official application "Themes"

The easiest and safest way to change the look of text is to use a regular tool from the manufacturer. Themes has the ability to find and install fonts that can dramatically change the way you experience the interface.

To get started, open the Themes app on your desktop. At the bottom of the screen, look for the Fonts tab (or the A icon), and there's a catalog of styles available. Note that color fonts are often labeled with special tags or have previews with multicolored letters.

The algorithm of actions is as follows:

• 🔍 Type “color,” “rainbow,” or “neon” into search for color options.
• 📥 Click the Download button next to your favorite option.
• ✅ After downloading, click "Apply" (Apply).
• 🔄 Restart the device if the system requests it for correct display.

It's important to understand that a store may restrict access to some resources depending on your region. If the search does not yield results, try changing the region in your phone settings to India or Singapore, where the directory is often richer. Regional restrictions are a common problem that users from CIS countries face.

After applying the new style, text throughout the interface, including settings and third-party apps, will change its appearance. If the result does not suit you, you can always return to the standard font in the same menu by selecting the default option.

Manual installation of fonts through Mi Settings

If the official directory does not have the right option, you can use the manual installation method, which allows you to embed files downloaded from third-party resources, such as 4PDA or specialized forums.

First, you need to download the font file (usually an archive or a file with the.mtz extension). After downloading, go to the phone settings. Find the Screen section or immediately open the Themes app. In the upper right corner, click on the profile icon (human).

Follow the instructions:

• 📂 Select “Local” or “Import».
• 📁 Find the downloaded file in the device memory.
• 🖌️ Click on the font file to apply it.

Some versions of MIUI require that the font file be in a specific folder, such as MIUI/theme or the root directory of internal memory. If the system does not see the file when you import, move it to the root of the storage.

⚠️ Note: When manually installed, make sure the font file is for your version of Android. Fonts from older versions may not work properly on Android 13 or 14.

This method is good because it gives access to a huge database of custom modifications that are not available in the official store. You can find fonts that mimic handwriting, neon glow, or even animation (although static color fonts are more common).

Use of third-party launchers for customization

If system methods do not produce the desired result or limit the choice, a third-party launcher is a great solution. Launcher is a program that completely replaces the desktop and often allows you to flexibly customize the appearance of widgets and icons, including the color of signatures.

Popular launchers like Nova Launcher, Microsoft Launcher or Smart Launcher have their own font settings, but they only change the desktop and app menu, but they don’t affect system settings or the “caller.”

To adjust the color of the text in the launcher:

1. Install the selected launcher from Google Play.
2. Make it the default default in the system settings.
3. Go to the launcher settings (usually a long tap on the desktop).
4. Find the "Look" or "Font and display" section.
5. Select the color of the icons from the palette.

The advantage of this method is that it is completely safe for the system, and even if the launcher falls or is deleted, the system fonts will remain intact, ideal for those who are afraid of disrupting the system interface.

Compatibility table of MIUI methods and versions

Not all methods work equally well on different versions of firmware. Below is a table that will help you navigate the available features for your model.

As you can see from the table, the official store is the most reliable way to cross all versions. With the release of HyperOS, security policies have been tightened, so manual methods can work unstable.

Possible problems and ways to solve them

Experimenting with the appearance of the phone can be a problem, and the most common problem is that the characters are not displayed correctly, instead of letters, you can see rectangles or question marks, which means that the font file does not contain a table of encoding for Cyrillic or other languages.

Another problem is the theme reset, and when you reboot, the phone may return to its standard look, which often happens if the typeface you have installed conflicts with your current theme, so try changing the theme to the one you want to use, or using the standard theme to leave the font.

To diagnose problems, use the following steps:

• 🔄 Perform a complete reboot of the device.
• 🗑️ Remove the recently installed font through the “Subjects” menu» -> «Profile» -> «Fonts».
• 📲 Check for system updates in the About Phone section».

⚠️ Warning: If the phone stopped responding to touches after installing the font, try resetting to factory settings via Recovery Mode, but remember that this will delete all data.

Also worth mentioning is the impact of color fonts on autonomy. Although the impact is minimal, complex graphic elements of a typeface may theoretically consume a little more CPU resources when rendering text, in practice this is imperceptible.

💡

In most cases, problems are solved by returning to the standard font through the Themes menu or rebooting in Safe Mode.
