Thanks for the report. The difference in behavior appears to be due to a
change in Tk. Using the python.org 3.7.2 or .3 installers which use Tk 8.6.8,
the colors are displayed. But if I use a Python linked with Tk 8.6.9, the bars
are not colored. You can run the following commands in Python to verify which
version of Tk is in use:
import tkinter
root = tkinter.Tk()
root.tk.call('info', 'patchlevel')
In any case, there isn't likely anything Python can do about it as tkinter is
pretty much a thin wrapper around calls to Tk and it's difficult to know what
the expected Tk behavior is. If you want to pursue this issue, I suggest
bringing it up on a Tk forum or checking whether there is a Tk issue about it.
But I had luck! Doing a quick search, I found this Tk ticket which seems to
describe your problem and does confirm that the behavior change was introduced
in 8.6.9:
