The output should manipulate colors using the **flag**`--color=<color> <substring to be colored>`, in which `--color` is the flag and `<color>` is the color desired by the user and `<substring to be colored>` is the substring that you can chose to be colored. These colors can be achieved using different notations (color code systems, like `RGB`, `hsl`, `ANSI`...), it is up to you to choose which one you want to use.
