Are real the advantages of using a dark theme while programming?
Is often read that dark theme is better for your eyes, but this does not have why to be true if you use the computer in a well illuminated room.
It is true is a know standard to have the terminal on white text over dark background, but when using for example Termux under the sun light the advantages of using a dark theme are no longer so real.
I think if you use the terminal in a smartphone is often more suitable to have it with a light background to be able to see better under the sun light.
I think this should be also matter of user choice, not a single style solution can suit all users, having only a way to see for example a webpage is a accesibility issue by itself since some disabilities/users have needs which are direct opposite between them.
