|
desired by the user.

|
|
|
|
- The colors can be done using different notations (color code systems, like `RGB`, `hsl`, `ANSI`, ...), its up to you to
|
|
|
|
|
choose which one you want to use.
|
|
|
|
|
- You should be able to specify a single or a set of letters you want to be colored (use your imagination for this one).
