A listbox can only scroll text. So, to display a colored word you would use
the "itemconfig" method to change the background and foreground of each
element individually.
For example:
for index, color in enumerate(colors):
listbox.insert("end", color)
listbox.itemconfig(index, foreground=color)
If you really want to create a list of widgets, you'll have to either embed
the widgets in a canvas, put the widgets in a frame and put the frame in a
canvas, or put the widgets in a text widget (canvas and text widgets being
the two widgets that support vertical scrolling)
