ANSI Escape Color Code di support di IDE (NetBeans & Eclipse) serta Terminal di Linux & Mac, namun untuk Command Prompt (CMD) Windows, karena tidak mendukung ANSI Code secara default. Untuk itu kita perlu menambahkan Library khusus untuk mengakomodir hal ini. Salah satunya adalah dengan memakai Library Jansi.
