I have just installed SageMath 8.7 on my Windows-10 laptop and want to learn it. The font colour of the prompt and of the typed numbers is dark blue on the black background, totally unreadable. Google search delivers tons of such complaints about bash/pythin/mintty/cygwin command lines. All suggest to edit some configuration files, which are hardly possible to locate in SageMath, neither in the SageMath installation directory, nor in my user home directory. There is a file ".sage\profile_default\ipython_config.py" in my Windows home, containing the line c.TerminalInteractiveShell.colors = 'Linux' Changing this line has no effect.
