Went to use my tablet the other day and pressed home button and the screen displayed as normal but in negative colours, isn’t the negative setting in settings
Check Settings –> Accessibility –> Vision There is a section in there with a check box for “Negative Colors”.
I believe your display settings are off. Go to settings>accessibility, then go down to the bottom where it says display. Make sure your color correction is off, and also make sure your inverted colors option off. If this doesn’t fix it, go to backup & reset, and do a factory reset. Make sure you backup anything important before reseting. Hope this helps.
