How to change UI colors for gitk?

Question

I use gitk for keeping an eye onto branches, commits and so on ... I am running Ubuntu 14.04. and noticed that the background color of the branch label is different in comparison to what I am used to on another machine running Ubuntu 13.10. Currently I have Git 1.9.3 installed.

Is there a way to customize the background color of the branch label in gitk?

Answer 1

That appears to be the headbgcolor, which is not available from the GUI colour settings.

Close gitk, then modify ~/.config/git/gitk and change

set headbgcolor green 

to some other colour. Hex codes appear to be supported unquoted, e.g.

set headbgcolor #123456 

Answer 2

For Windows, you need to change headbgcolor in your %HOMEPATH%\.gitkhidden file.
