How to change color in git diff

I was able to change color for old, new, and meta regions, but I can't find the option to change the color of @@ -1 +1, 2 @@ (in the picture) and the color of the red square at the end (in the picture).

git diff output

Solution

  • Hunk header color option is called color.diff.frag.

    Whitespace at the end is called color.diff.whitespace.
    Whitespace uses background color so you have to set both colors (thanks @IGRACH)

    You can test it like this:

    git -c color.diff.frag=yellow -c color.diff.whitespace='cyan cyan' diff

    For completeness, the rest of options are:

    • context (context text - plain is a historical synonym)
    • meta (metainformation)
    • frag (hunk header)
    • func (function in hunk header)
    • old (removed lines)
    • new (added lines)
    • commit (commit headers)
    • whitespace (highlighting whitespace errors)
    • oldMoved (deleted lines)
    • newMoved (added lines)
    • oldMovedDimmed
    • oldMovedAlternative
    • oldMovedAlternativeDimmed
    • newMovedDimmed
    • newMovedAlternative
    • newMovedAlternativeDimmed
    • contextDimmed
    • oldDimmed
    • newDimmed
    • contextBold
    • oldBold
    • newBold

    Available colors: normal, black, red, green, yellow, blue, magenta, cyan, white and default
