Use of # in HEX color format

Question

What does # mean in the following code?

function rndm_colour(){
  var letters = '0123456789ABCDEF';
  var color = '#';
  for (var i = 0; i < 6; i++) {
      color += letters[Math.floor(Math.random() * 16)];
  }
  return color
}

It's creating a random colour in the HEX color format, which requires a `#` as a prefix — Nick Parsons, Aug 01 '20 at 03:12

It looks like this function generates a random HTML Color code, which begins with a #.

The code creates a random color in the HEX format. All HEX colors always start with a "#".
