All of the information is there in the text; the color and font are just
supposed to make it easier to see.  As for the diff text itself, I
didn't remember what it meant myself, so I looked it up.

It seems the diff format shown is that produced by 'git-diff --cc',
which makes a "compact combined diff".  It only shows conflicting
changes.  Each column on the left represents the changes from a
different parent.

Hope that helps,
Jonathan
