On recent versions of macOS (sometime between Catalina and Sonoma 14.5), the default Hovertip foreground color changed from black to white, thereby matching the background. This might be a matter of matching the white foreground of the dark-mode text. The unreadable result is shown here (GH-120083 (comment)).
The foreground and background colors were made parameters so we can pass different colors for future additional hovertips in IDLE.
(cherry picked from commit 5a7f7c4)
