FIRST: a number of DrRacket color schemes are available
    from the DrRacket menu,
    *   selecting "Preferences",
    *   clicking on "Colors" and "Color Schemes" near the top.

And you can design/customize your color preferences as well.

BUT for another dark mode option,
a previous semester's CS 111 student, Isaiah Angulo recommended
    and provided the following instructions:

*   BUT you need to use raco, from a terminal (command line), 
    to install the additional Racket color schemes
    described;

https://beautifulracket.com/setting-the-mac-os-path.html
https://beautifulracket.com/setting-the-windows-path.html

    (for both Mac and Windows! BUT I only tried the Mac ones)

    ...are for a different package, Beautiful Racket, BUT have directions
    I found useful for setting the path (where the computer LOOKS to
    find commands) so that raco can be found and used!

========
https://beautifulracket.com/setting-the-mac-os-path.html

*   ...describes how to set the path for Mac OS so you can reach raco from
    the terminal

    I ended up using the command:

sudo sh -c 'echo "/Applications/Racket v7.8/bin" >> /etc/paths.d/racket'

    ...to add Racket 7.8's bin to my path (with my Mac OS password
    entered when prompted)

    THEN open a new Terminal!! YUP, that works!

    from the above link:   

    "This command puts the path to Racket in a new file called
    /etc/paths.d/racket, which will be automatically loaded in the
    future."

*   This is supposed to have directions for setting the Windows
    PATH:

========
*   NOW, from a Terminal, I CAN run:

    raco pkg install git://github.com/tuirgin/base16-drracket

*   NOTE: BUT I found the new colors under
 
    DrRacket -> Preferences

    not 

    Edit -> Preferences

    ...is that a Mac vs. Windows thing? or an error in

    ...not sure!

========
*   But feel free to try this out, if you would like!

********
FINAL NOTE!!!!
*   IN LAB: if you are sharing the screen, and have changed the
    DrRacket color scheme, ASK your pair partner and MAKE SURE they are
    able to SEE your chosen color scheme! 

    ...it may NOT be visible in Zoom, on a smaller screen, with
    different vision abilities, with different lighting conditions,
    etc.!
