There are a few ways to change the color of your text messages on Android. The first way is to use the Settings app and select the Text Message section. There, you can change the color of your messages to any color you like. The second way is to use a third-party app such as ColorSync or QuickType Pro. These apps allow you to change the color of your text messages on a per-message basis. The third way is to use a text editor such as Notepad or WordPad and type in a few lines of code that will change the color of your messages.
