Answer 1

Based on Jacobs answer I made a loadbar. This one is from green to red, but you can change the colors. For those interested here's my code and the jsfiddle ( http://jsfiddle.net/rxR3x/ )

var percentColors = [
    { pct: 0, color: '#00FF00' },   { pct: 3, color: '#12FF00' },   { pct: 6, color: '#24FF00' },
    { pct: 10, color: '#47FF00' },  { pct: 13, color: '#58FF00' },  { pct: 16, color: '#6AFF00' },
    { pct: 20, color: '#7CFF00' },  { pct: 23, color: '#8DFF00' },  { pct: 26, color: '#9FFF00' },
    { pct: 30, color: '#B0FF00' },  { pct: 33, color: '#C2FF00' },  { pct: 36, color: '#D4FF00' },
    { pct: 40, color: '#E5FF00' },  { pct: 43, color: '#F7FF00' },  { pct: 46, color: '#FFF600' },
    { pct: 50, color: '#FFE400' },  { pct: 53, color: '#FFD300' },  { pct: 56, color: '#FFC100' },
    { pct: 60, color: '#FFAF00' },  { pct: 63, color: '#FF9E00' },  { pct: 66, color: '#FF8C00' },
    { pct: 70, color: '#FF7B00' },  { pct: 73, color: '#FF6900' },  { pct: 76, color: '#FF5700' },
    { pct: 80, color: '#FF4600' },  { pct: 83, color: '#FF3400' },  { pct: 86, color: '#FF2300' },
    { pct: 90, color: '#FF1100' },  { pct: 93, color: '#FF0000' },  { pct: 96, color: '#FF0000' },
    { pct: 100, color: '#FF0000' }
];
var getColorPercent = function(selector, percent, time){
    var i = 0;
    var percentInterval = setInterval(function() {
         i++;
         if(percent >= percentColors[i].pct) {
            console.log(percentColors[i].color);

    $(selector).animate({width:(200/100)*percent}, time);
}
getColorPercent('#loadbar_storage', 100, 1500);
