The color theme of the app can be changed from
There are four color themes to choose from:
|Bright colors suitable for use in daylight||No dimming|
|Green and Blue colors are subdued by about 50%||Dimmed|
|Only Red color is used||Dimmed|
|Only Green color is used||Dimmed|
Night color theme is designed to preserve dark adaptation.
Green color theme can be useful in certain scenarios like observations under a bright full moon.
Note: The above color theme only applies to the app and not to OS provided windows such as the onscreen keyboard. It is a good idea to change your keyboard theme to a dark one, to avoid being suddenly blinded when the keyboard pops up within the app. Android 10+ also introduced a system-wide
Dark Themeoption, which is a great way to make all such windows dark by default.
