+       Find the color setting for `name` (e.g. `color.diff`) and output
+       "true" or "false".  `stdout-is-tty` should be either "true" or
+       "false", and is taken into account when configuration says
+       "auto".  If `stdout-is-tty` is missing, then checks the standard
+       output of the command itself, and exits with status 0 if color
+       is to be used, or exits with status 1 otherwise.

+--get-color name default::
+
+       Find the color configured for `name` (e.g. `color.diff.new`) and
+       output it as the ANSI color escape sequence to the standard
+       output.  The optional `default` parameter is used instead, if
+       there is no color configured for `name`.
