That would indicate you have one of the Invert options selected. In the Accessibility section, you should see the settings below.

Even if dark is on, it wouldn't make for example the Facebook App orange. I thought of this and tried it before I made the suggestion I made.

Do all of your apps have different colors?

Can you post a screenshot?

Go to Settings/Display & Brightness and tap on “Light"

Try going to Settings > Accessibility > Display & Text Size

If anything beneath Increase Contrast is turned on, turn it off.

In addition to the advice posted above: Please check Settings - Accessibility - Display & Text Size - Smart Invert = ?? Classic invert = ??
