Hello trixaseeklol,
Welcome to Apple Support Communities. Do you use any filters or display accommodations? If so, that may be what is impacting your display colors. Check out the following sections from Use display and text size preferences on your iPhone, iPad, and iPod touch - Apple Support that may be particularly helpful.
"Turn on Invert Colors
If you benefit from viewing items against a dark background, you can use Invert Colors to change how content is displayed on your screen.
To use Invert Colors, open the Settings app, then tap Accessibility > Display & Text Size. Turn on Smart Invert or Classic Invert.
"Turn on Color Filters
If you have color blindness or other vision challenges, you can use Color Filters to help you differentiate between colors. Color Filters can change the look of things, like pictures and movies, so you might want to use it only when needed.
Open the Settings app, then tap Accessibility > Display & Text Size > Color Filters. You'll see three examples of color spaces to help you select an option that fits your needs. Swipe left or right on the examples to find a filter that works best for you."
If the same continues, does this happen in all apps or any in particular?
Take care.
