change color of ion range-slider handle

Question

If I try to change the default color of ion range-slider (available here: https://github.com/IonDen/ion.rangeSlider) from red (default) to blue, like that:

.irs-slider.single {
    background: blue;
}

It becomes square:

(originally it looks like a thin red line: )

What am I doing wrong?

DEMO

        type: "single",
        min: 0,
        max: 1000,
        from: 200,
        to: 500,
        grid: true
    });

.irs-slider.single {
    background: blue;
}

i change with js script like this, i hope you will use it

onChange: function(data) {
let id = $(data.slider[0]['parentNode']).attr('id');

if (data.from < 50) {
  $('#' + id).find('.irs-bar--single').css('background-color', '#ee22fa');
  $('#' + id).find('.irs-single').css('background-color', '#ee22fa');
  $('#' + id).find('.irs-handle > i:first-child').css('background-color', '#ee22fa');
} else if (data.from <= 60) {
  $('#' + id).find('.irs-bar--single').css('background-color', '#ed5565');
  $('#' + id).find('.irs-single').css('background-color', '#ed5565');
  $('#' + id).find('.irs-handle > i:first-child').css('background-color', '#ed5565');
}
}

$('#traffic_percent').ionRangeSlider({
  min: 0,
  max: 100,
  type: 'single',
  prefix: "%",
  from: $('#traffic_percent').val(),
  onChange: function(data) {
    var color = $('#traffic_percent').val();

    if (color > 50) {
      $('#your div id').find(".irs-bar").css("background", "#6fda43");
    } else {
      $('#your div id').find(".irs-bar").css("background", "#fb8c8a");
    }
  }
});

The background is an image (https://cdnjs.cloudflare.com/ajax/libs/ion-rangeslider/2.2.0/img/sprite-skin-flat.png), so you cannot simply change the color. You can consider a gradient to create a similar image with the color you want. Since it's a simple line it should be easy.

$(".js-range-slider").ionRangeSlider({
  type: "single",
  min: 0,
  max: 1000,
  from: 200,
  to: 500,
  grid: true
});

.irs-slider.single {
  background: linear-gradient(blue, blue) center/2px 100% no-repeat;
}

Looking at the demo,the .single class is used in the tooltip element. However I can change the thin red color to blue like this:

.irs--flat .irs-handle>i:first-child {
    background: blue;
}
