Xiaomi Redmi 8 – budget smartphone with IPS-The screen is 6.22 inches, which is still popular today due to its balanced characteristics, but the factory color settings are not always satisfactory for users: Some complain about excessive coldness in the image, others about insufficient saturation in games or photos. In this article, we will discuss all the ways to adjust color reproduction on Redmi 8, including hidden features. MIUI, manual calibration and even correction through the engineering menu.
It's important to understand that customization is based on the firmware version. At the time of writing (2026), current versions of MIUI 12/13/14 for Redmi 8 offer different features. We'll take these nuances into account and show you how to achieve the perfect picture regardless of the updates, and you'll learn why colors can get lost after resetting and how to fix it without losing data.
Why the Redmi 8’s Factory Color Settings Aren’t Always Optimal
Smartphone makers, including Xiaomi, often customize screens to fit the “average” user. For Redmi 8, this means:
- 🔹 Default color temperature — 6500K (Neutral white, but many people think of it as "blueish".
- 🔹 Saturation is understated to save battery power (especially noticeable in read mode).
- 🔹 Automatic brightness correction often works incorrectly in low light.
- 🔹 The “For the Eyes” mode (blue filter) is turned on aggressively, distorting real colors.
Besides, IPS-The Redmi 8 has a limited color range (~95% sRGB), so the factory calibration may seem pale compared to the AMOLED-But that doesn't mean you can't improve the image.
Basic Color Temperature setting in MIUI
The easiest way to adjust the shades is to change the color temperature in the standard settings, which is responsible for the “warmth” of white, from cold blue (7000K+) to warm yellow (4000K).
To get on the menu:
- Open Settings (the gear icon on the main screen).
- Go to the Screen section.
- Select Color Temperature (in some versions of MIUI, the item is called Color Tone).
You will open a slider with three preliminary modes:
| Regime. | Temperature (K) | The effect | When to use |
|---|---|---|---|
| Warm. | ~4500K | Yellow tint, less blue light | In the evening, for reading, with fatigue of eyes |
| Standard. | ~6500K | Neutral white (factory setting) | Daytime use, viewing photos/video |
| Cold. | ~7500K | Bluish shade, high contrast | Bright lighting, games with dark tones |
Important: MIUI 14 for Redmi 8 may not have a color temperature slider — instead, only three fixed modes are available. This is a firmware restriction that is bypassed through the engineering menu (see section below).
Make sure that the "Standard" mode is enabled"|Turn off Adaptive Brightness for fine tuning|Check if the reading mode is active"|Turn off the "Vision Protection" (blue filter) temporarily.-->
Advanced settings: Color calibration manually
If pre-modes are not enough, MIUI has a hidden manual RGB calibration feature that allows you to separately adjust the intensity of the red, green and blue channels, which is not available in all versions of the firmware, but on Redmi 8 it can be activated through the developer settings.
Instructions:
- Activate Developer Mode: Go to Settings → About Phone. Tap 7 times on MIUI Version (you will be notified "You're a developer!").

We recommend changing the values by no more than ± 15 units.
Photographer’s advice: If you often view photos on Redmi 8, set a balance of R:100, G:95, B:90 – this will bring the picture closer to the sRGB standard and reduce the “blue” in dark photos.
What to do if calibration is not available?
Engineering menu: hidden screen parameters
For advanced users, Xiaomi leaves access to the MTK Engineer Mode, where you can fine-tune the gamut, contrast, and even calibrate the light sensor. Careful: incorrect changes can lead to display failures!
How to open the engineering menu:
- Open the Phone app.
- Enter the combination: ##36446337## (for MediaTek processors used in Redmi 8).
- Select the Hardware Testing section → LCD.
How to return colors after updating:
- Check the firmware version in Settings → About Phone. If it is MIUI 12 or later, use the instructions in the Advanced Settings section.
- Reset the screen settings to factory: Settings → System → Reset settings → Reset screen settings.
- If the colors remain distorted, calibrate through the engineering menu (see above).
Critical information: in firmware MIUI 14.0.2.0 and later for Redmi 8, the color temperature slider is removed in the standard settings. The only way to get it back is to roll back to the standard settings. MIUI 12 or use ADB-commands (requires PC).
💡
After updating the firmware, always check the color settings – even minor updates (for example, from MIUI 13.0.1 to 13.0.2) can reset the calibration.
Third-party apps to customize color
If standard MIUI tools are not enough, you can use third-party utilities, which fall into two categories:
- No root rights (limited functionality): Night Shift is an analogue of the For Eye mode with flexible settings. Blue Light Filter is a blue light filter with intensity adjustment.
With root rights.
- Screen Balance is an accurate calibration of RGB, gamma and contrast.
- Kernel Adiutor – Change the color profile at the core level.
Don’t try to fix this by changing the RGB manually.
