for example, you can accentuate error messages like below:

color256_t const white = color256_of_gray(23);
color256_t const   red = color256_of_rgb(5,0,0);
fprintf_256colored(white, red, stdout
                  , "[ERROR] no such file or directory (%s)"
                  , path_to_dir);

then, users would see the red-colored error message.
