Dark mode is an alternative color scheme included in many operating systems and apps. Dark mode color schemes use primarily dark colors rather than more traditional light themes. The main advantage of dark mode is that it makes your device screen appear much less bright when it’s being used in the dark, making it a lot easier on your eyes.
For devices with OLED or AMOLED screens, enabling dark mode can even provide power savings over traditional color schemes. This is because these screen types produce light directly from the individual pixels, therefore, producing dimmer colors requires less power. Traditional LCD screens don’t see the same power savings. This is due to the fact that each pixel simply filters the required colors of light from the back-light which is always on at a set brightness level.
To configure dark mode in the Opera browser on Android, you need to go through the in-app settings. To be able to access the in-app settings, tap the Opera icon in the bottom-right of the app.
In the popup menu, you can toggle dark mode on or off by tapping “Night mode”.
To configure the settings, tap “Settings” at the bottom of the menu.
In the settings, tap the “Night mode” label to configure the dark mode settings.
There are 6 dark mode settings to choose between. “Color temperature” applies a blue light filter, which is supposed to reduce the effect of the light from the screen on your sleep patterns but also negatively affects the appearance of web pages.
“Dimming” further dims the appearance of the screen. “Use dark theme” allows you to select if the browser interface uses a dark theme when Night mode is enabled. “Dark web pages” changes the appearance of web pages making the backgrounds black and the text white.
Tip: “Dark web pages” may cause problems on some webpages where transparent images with dark or black segments are used.
“Dim keyboard” dims the keyboard inline with the rest of the app, although you will need to grant Opera permission to dim the keyboard.
“Schedule” allows you to configure a schedule for Night mode to be automatically enabled and disabled.
Alternatively, if you only want Opera to always use a dark interface theme, you can tap on “Appearance” on the main settings list, then select the “Dark” theme at the top.
