Maybe partly because I work with black-ink-on-white-paper terminal setting, and maybe partly because my color perception is suboptimal, I learned to use "[diff.color] old = red reverse", because non-bold red letters do not stand out enough. Perhaps you may want to try reverse output to see how well it makes them stand out for you. I do not think if configurability like "git diff" has is necessary; it would be overkill. I personally do not mind more noise "?!" around the keyword, especially since these are only shown when there are problems detected.
