Changing the color of the jquery ui slider when moving it

I was looking for an answer to a question on how to do this, and I cannot understand it (even looking at the jQuery ui documentation). When I move the slider from left to right, I want the section on the left side of the slider to change to orange (instead of gray by default).

JQuery jQuery theme created css below. Presumably, the background color .ui-widget-header will control this, but it doesn't look like that. Also, background color is not added for any other class. Any idea how I fix this so that you get a different color when moving horizontally?

JQUERY:

    $(document).ready(function(){

        $("#tasks_time").slider({
            value: 1,
            min: 0,
            max: 72,
            step: 1,
            slide: function() {
                update();
            }
        });

        $("#tasks_done").slider({
            value: 5,
            min: 0,
            max: 1000,
            step: 10,
            slide: function() {
                update();
            }
        });

HTML:

    Finish these items in <span id="curr-tasks_time" class="calc_number">1</span> hours

    <div id="tasks_time">
    </div>

CSS

.ui-widget-content { border: 1px solid #ccc; background: #ff9900 url(images/ui-bg_flat_100_ff9900_40x100.png) 50% 50% repeat-x; color: #222222; }
.ui-widget-header { border: 1px solid #aaaaaa; background: #797979 url(images/ui-bg_highlight-soft_75_797979_1x100.png) 50% 50% repeat-x; color: #222222; font-weight: bold; }

.ui-slider { position: relative; text-align: left; }
.ui-slider .ui-slider-handle { position: absolute; z-index: 2; width: 1.2em; height: 1.2em; cursor: default; }
.ui-slider .ui-slider-range { position: absolute; z-index: 1; font-size: .7em; display: block; border: 0; background-position: 0 0; }

.ui-slider-horizontal { height: .8em; }
.ui-slider-horizontal .ui-slider-handle { top: -.3em; margin-left: -.6em; }
.ui-slider-horizontal .ui-slider-range { top: 0; height: 100%;  }
.ui-slider-horizontal .ui-slider-range-min { left: 0;  }
.ui-slider-horizontal .ui-slider-range-max { right: 0;}

Here is an example

    if ( colorVal < 50 ) {
                myRed = 255;
