Hmm. I think this is actually due to the way the pager displays colors.
Try this:
git --no-pager log -1 --format='foo%C(red)%+an'
I see the committer name on its own line in read, as expected. Now try
the same thing with a pager:
git log -1 --format='foo%C(red)%+an'
I see no color.
The actual output sequence is (<red>, <newline>, <author>). So
presumably what is happening is that the pager does not let color from
the previous line impact to the next line.
Unfortunately I don't know if there's an easy workaround. What you
really want is to apply the "+" magic to a whole section of the string.
You can do that with git-for-each-ref's format, like:
%(if)%D%(then)%n%C(red)%D%(end)
but the two formats are not (yet) unified. There's interest in doing
that, and an Outreachy intern worked on it over the winter, but there's
still a long way to go.
