  Hello,

  I have created a simple example for you. First, I created a new custom list with three column: A (number), B (number), SUM (calculated field: A + B). In Forms Designer I added my fields into the form and set css-class of SUM field to 'calc-field'. I will use this class in selector to set background-color:

  

   

  Next, I declared the following CSS classes in Forms Designer's CSS-editor:

  .bg-red {
    background-color: red;
  }
  
  .bg-green {
    background-color: green;
  }
  
  .bg-yellow {
    background-color: yellow;
  }
  

  I will use them to set background color based on the SUM field value. Next, I added the following js-code to JS-editor:

  function setBgColor() {
    $('.calc-field').removeClass('bg-red bg-yellow bg-green')
    
    var calcValue = parseFloat(fd.field('SUM').control()._el().text());
    if (calcValue <= 50) {
      $('.calc-field').addClass('bg-red');
    }
    
    if (calcValue > 50 && calcValue < 100) {
      $('.calc-field').addClass('bg-yellow');
    }
    
    if (calcValue == 100) {
      $('.calc-field').addClass('bg-green');
    }
  }
  
  function updateSum() {
    var a = parseFloat(fd.field('A').control().value());
    var b = parseFloat(fd.field('B').control().value());
    fd.field('SUM').control()._el().html(a + b);
    setBgColor();
  }
  
  // updates calculated field value when value of field A is changed.
  fd.field('A').control().change(function() {
    updateSum();
  });
  
  // updates calculated field value when value of field B is changed.
  fd.field('B').control().change(function() {
    updateSum();
  });
  
  // sets background color of SUM field
  setBgColor();
  

  setBgColor function changes background of the calculated field based on its value. updateSum updates value of SUM field based on the current values of A and B and changes its background color. I call this function when value of the field A or B is changed. And in the latest line I call setBgColor to set initial background color of SUM field.
