ascii-art-color

Objectives

You must follow the same instructions as in the first subject but this time with colors.

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.

  • The substring to be colored can be a single letter or more
  • If the substring is not specified, the whole string should be colored.
  • The flag must have exactly the same format as above, any other formats must return the following usage message:
Usage: go run . [OPTION] [STRING]

EX: go run . --color=<color> <substring to be colored> "something"

Usage

$ go run . --color=red kit "a king kitten have kit"

For the example above, the substring kit in the word kitten and the word kit at the end should be colored.

If there are other ascii-art optional projects implemented, the program should accept other correctly formatted [OPTION] and/or [BANNER]. Additionally, the program must still be able to run with a single [STRING] argument.
