Color Themes
The color theme of the app can be changed from
Home Screen->Settings->Color ThemeMap Screen->Menu->Color Theme

There are four color themes to choose from:
| Theme | Colors | Navigation Buttons |
|---|---|---|
Day | Bright colors suitable for use in daylight | No dimming |
Dusk | Green and Blue colors are subdued by about 50% | Dimmed |
Night | Only Red color is used | Dimmed |
Green | Only Green color is used | Dimmed |
The Night color theme is designed to preserve dark adaptation.
The 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.
