RGB to hex and hex to RGB

Question

How to convert colors in RGB format to hex format and vice versa?

For example, convert \'#0080C0\' to (0, 128, 192).

Answer 1

For convert directly from jQuery you can try:

  function rgbToHex(color) {
    var bg = color.match(/^rgb\((\d+),\s*(\d+),\s*(\d+)\)$/);
    function hex(x) {
      return ("0" + parseInt(x).toString(16)).slice(-2);
    }
    return     "#" + hex(bg[1]) + hex(bg[2]) + hex(bg[3]);
  }

  rgbToHex($('.col-tab-bar .col-tab span').css('color'))
