Would you please change gitk to not hard-code Win32-specific color values when creating .gitk on a Win32 windowing system? Gitk stopped working for me on Cygwin when Cygwin changed from using a Win32 native version of tk to using the standard X11 version. The error was because gitk had previously created a .gitk file using Win32 specific color values: https://github.com/gitster/git/commit/1924d1bc0dc99cd3460d3551671908cc76 c09d3b I was able to work around the problem by replacing the Win32 specific colors in my .gitk file with the default colors gitk uses on other windowing systems.
