+diff.color::
+ When true (or `always`), always use colors in patch.
+ When false (or `never`), never. When set to `auto`, use
+ colors only when the output is to the terminal.
+
+diff.color.<slot>::
+ Use customized color for diff colorization. `<slot>`
+ specifies which part of the patch to use the specified
+ color, and is one of `plain` (context text), `meta`
+ (metainformation), `frag` (hunk header), `old` (removed
+ lines), or `new` (added lines). The value for these
+ configuration variables can be one of: `normal`, `bold`,
+ `dim`, `ul`, `blink`, `reverse`, `reset`, `black`,
+ `red`, `green`, `yellow`, `blue`, `magenta`, `cyan`, or
+ `white`.
