How to cancel QQ color font? Can you tell me more about it?

In the font color settings of your QQ, just change it to black. It's in the box where you enter the text. A click of the mouse will pop up many colors. You must modify the settings before.

You're not talking about some colorful words in your QQ expression, are you? As long as you type those words, they will automatically become colored, and some will move. It's beautiful, but the other party may not see it. If this is the case, you should uncheck the QQ expression "Use custom expression".

The color font is not a problem with your software, but because your QQ settings are saved on the QQ website. If you don't change the setting, it won't change. It has nothing to do with reinstalling software QQ.
