I've setup grep colors in my ~/.bashrc :
export GREP_COLORS='ms=01;34:mc=01;34:sl=:cx=:fn=35:ln=32:bn=32:se=36'
They work for
grep --color=autogrep --color=always
Unfortunately, those custom colors are ignored by:
git grep --color=autogit grep --color=always
How to make git grep to use above $GREP_COLORS colors ?

greputility, it has its own internal command which is calledgit grepand has similar but not identical options. – Gilles Feb 2 '12 at 1:16
