77 Colors are very pretty.
79 This plugin causes certain prints, warns, and errors to be colored. Generally
80 the return value(s) of each line will be colored green (you can override this
81 by setting C<< $_REPL->normal_color >> in your rcfile). Warnings and
82 compile/runtime errors will be colored with C<< $_REPL->error_color >>. This
83 plugin uses L<Term::ANSIColor>, so consult that module for valid colors. The
84 defaults are actually 'green' and 'bold red'.
