the display of colors on the command line is not in teh scope of R but depends on the terminal you're using. If you're using Linux and a bash terminal, you can try to print control characters for colors like described in Arch Wiki: https://wiki.archlinux.org/index.php/Color_Bash_Prompt#List_of_colors_for_prompt_and_Bash
I don't know whether Windows' "cmd"-terminal can print colors.
