Hi and welcome to the Forum!

You haven't inadvertently turned White on Black on have you? Have a look in Settings - General - Accessibility - White on Black and see if it's turned on here. If that's not ON have a look lower to Triple Click Home and what has been set up here, there are a few different options. This is activated by triple pressing the home button and is easy to activate by mistake. Hope this helps, let us know.
