Different Theme/Theming Colors

[knakamura8]

Is your feature request related to a problem? Please describe.
No.

Describe the solution you'd like
Android, as well as many android apps, has different theme/accent color schemes such as purple, orange, etc. Considering how much time some users such as myself spend within the app, I think it would be pleasant to have at least a few more options aside from light, dark, and black modes. Seeing as it is just a color setting, and that theming is already enabled within the app, I think there could be a lot of UI/UX gain for what I do not think should amount to much programming effort (though perhaps I am incorrect here). Perhaps as a stretch goal, the user could type in and/or use a color-picker for a custom hex for the background color, and a custom hex for the foreground color.

Describe alternatives you've considered
I have not looked at the codebase myself.

Additional context
