This however requires a long command:
```
$ git -c color.diff.new='bold reverse green' \
-c color.diff.old='bold reverse red' \
diff --no-index -U0 --no-color \
--word-diff=color --word-diff-regex=. \
<file1> <file2>
```
An alternative for integration with git is `diff-so-fancy`
## ASCII
* `vimdiff`
