<p>Generates a random hexadecimal color code.</p>
<p>Use <code>Math.random</code> to generate a random number and limit that number to fall in between 0 and 16 using <code>Math.floor</code>. Use the generated random number as index to access a character from 0 to F. Append it to <code>color</code> till the length is not <code>7</code>.</p>
