Thank you for your support of the Xiaomi product. The phone has been inspected strictly before leaving the factory, so you can rest assured of use. Limited by OLED display materials, the display screen can have slight color changes at different brightness levels, which is a normal phenomenon.
You can try the following ways to adjust the screen colors:
1. Go to [Settings];
2. Tap [Display & brightness];
3. Select [Color scheme]. Adjust the position of the point on the color temperature wheel to meet your desired screen display effect.
