A Co-Worker told me about this hidden setting… It essentially inverts the default color pallet of your phone. At first I thought it was just the colors of the app icons to make them anti-apple, but then I quickly realized it does it to all the menus in the apps themselves as well as pictures.
This invert trick turned the blues to a cool orange color and made pics of my son’s look like zombie kids… perfect for halloween if you can stand browsing web pages and what not like this… worst case you can always change it back.
Here’s where to toggle the setting:
Settings > General > Accessibility > Invert Colors
Wha-La… a halloween interface!
