JavaScript code for converting RGB to hex:

var color = '';
$('div').click(function() {
  var x = $(this).css('backgroundColor');
  hexc(x);
  console.log(color);
})

function hexc(colorval) {
  var parts = colorval.match(/^rgb\((\d+),\s*(\d+),\s*(\d+)\)$/);
  delete(parts[0]);
  for (var i = 1; i <= 3; ++i) {
    parts[i] = parseInt(parts[i]).toString(16);
    if (parts[i].length == 1) parts[i] = '0' + parts[i];
  }
  color = '#' + parts.join('');
}
