If Statements are set up to work with 1 or 2 options.

If we need mutliple options, we need to nest multiple if
  statement together.

   0 -  63 :   color 1  (blue)
  64 - 127 :   color 2  (green)
 128 - 191 :   color 3  (cyan)
 192 - 255 :   color 4  (yellow)

One solution is to have an if statement as the
   body of the else clause(s).
   However, the required identation can lessen the readability
      of the code.

Another Solution is to us thre elif keyword.
   This teads to make the code more readable.
