// e/E, f/F, g/G : for float and double;
// s : for string;
// p : for any type, write address;
// a : automatic, for any type, write in the default format;
// Namely the standard ones exception 'n', and plus 'a'.
//
// Optional 'color' format will be in form of: [foreground:background], [foreground]
// or [:background]. The supported color name format will depend on the color printing
// handle. Mininum requirement is the support of the following 8 color names:
// black, white, red, green, blue, yellow, magenta, cyan.
