You can use following method to validate css color

  1. Create a temporary element
  2. Set any color using css('backgroundColor', 'white')
  3. After apply with the input value as backgroundColor using d.css('backgroundColor', this.value);
  4. Check the the color is changed or entered value is same that we are initially set, in that case it's a valid color

$('#input').keyup(function() {
  if (this.value.trim()) {
    var d = $('<span/>')
      .css('backgroundColor', 'white')
      .css('backgroundColor', this.value);
    $('#op').html(this.value + (d.css('backgroundColor') == '' && this.value + (d.css('backgroundColor') != 'white' && d.css('backgroundColor') != 'rgb(255, 255, 255)') || /^white$/i.test(this.value) ? ' is valid' : ' is not valid'));
  } else
<script src=""></script>
<input type="text" id="input">

<div id="op"></div>
