Turtle Graphics is built upon a library call Tkinter, which is itself
built upon a library called Tk.

Tk recognizes many strings as color names (e.g., 'red'). The strings
recognized by Tk and their 8-bit RGB values are listed below. You don't
need to use the RGB values; just use the names in the leftmost column.

Don't forget that for Python, the name must be a STRING
and hence enclosed in quote marks, e.g. 'alice blue'.
