Because true internet ninjas browse at night
Opera Mini is designed to be used comfortably during the day, even in sunny areas. However, when you’re browsing during the night, a bright screen can more easily tire your eyes. So, is there a solution for that? Actually, for iOS users, there is. There’s a special setting on iPhone and iPad that inverts the colors on the screen — including within the Opera Mini app.

When you’re ready to go back to normal colors, just triple-click the home button again.
