title: Difference between ANSI color?
body: <p>I was searching about changing output color for console in NetBeans and found <a href="https://stackoverflow.com/questions/5762491/how-to-print-color-in-console-using-system-out-println">this</a> post. 
  I tried the first answer and worked perfectly for changing colors. I tried the fifth answer and... worked too. </p>
  
  <p>My question is: why the strings designated for every color are different in first and fifth? </p>
  
  <p>First answer's example:</p>
  
  <pre><code>public static final String ANSI_BLUE = "\u001B[34m";
  </code></pre>
  
  <p>Fifth answer's example:</p>
  
  <pre><code>public static final String BLUE = "\033[0;34m";    // BLUE
  </code></pre>
  
  <p>I made a little research but I really couldn't figure why.</p>
  
  <p>I appreciate an answer or help in pointing me to understand it.</p>
