Make sure all the colors work well depending on darkmode or light mode on the computer

Just a note that the colours displayed on the terminal are controlled by the terminal itself, so this might be a bit tricker. For instance if the OS is in dark mode then it might be making the terminal invert / change some colours on it's own.

I feel like we should be able to define a style class or style theme

I like the idea of a style class or theme. Then we could have a "light" and "dark" mode?
