Text message display screen is black with white letters

[AC Question]

The screen that shows you all the people you sent a text to has all of a sudden turned black with white letters. How do i change it back?

Is the rest of the device also in negative colours? If not, find the messaging app, clear cache, force stop app and restart the device. If yes, find settings, accessibility, vision, and negative colours... If that fails, come back and tell us more so we can troubleshoot with you...
