title: How can I use colors in ES6 template strings?
body: <p>In ES5 and below, I could use ANSI colors in JS strings such as </p>
  
  <p><code>"\033[31m Hello World\033[0m"</code>.</p>
  
  <p>With ES6 template strings, I get the error:</p>
  
  <pre><code>SyntaxError: Octal literals are not allowed in template strings.
  </code></pre>
  
  <p>I have tried <code>\u{31m}</code> but it didn't work either.</p>
